MPLS Command Reference for Cisco 8000 Series Routers

adjustment-threshold (MPLS-TE)

To configure the tunnel bandwidth threshold to trigger an adjustment, use the adjustment-threshold command in MPLS-TE automatic bandwidth interface configuration mode. To disable this feature, use the no form of this command.

adjustment-threshold percentage [min minimum bandwidth]

no adjustment-threshold percentage [min minimum bandwidth]

Syntax Description


`percentage`	Configures the bandwidth percent threshold to trigger an adjustment if the largest sample percentage is higher or lower than the current tunnel bandwidth. The range is from 1 to 100. The default is 5.
min `minimum bandwidth`	(Optional) Configures the bandwidth change value to trigger an adjustment. The tunnel bandwidth is changed only if the largest sample is higher or lower than the current tunnel bandwidth, in kbps. The range is from 10 to 4294967295. The default is 10.

Command Default

percentage: 5

minimum bandwidth: 10

MPLS-TE automatic bandwidth interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

If you configure or modify the adjustment threshold while the automatic bandwidth is already running, the next band-aids application is impacted for that tunnel. The new adjustment threshold determines if an actual bandwidth takes place.

Examples

The following example configures the tunnel bandwidth threshold to trigger an adjustment:


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# auto-bw
RP/0/RP0/CPU0:router(config-if-tunte-autobw)# adjustment-threshold 20 min 500

admin-weight

To override the Interior Gateway Protocol (IGP) administrative weight (cost) of the link, use the admin-weight command in MPLS-TE interface configuration mode. To return to the default behavior, use the no form of this command.

admin-weight weight

no admin-weight weight

Syntax Description


`weight`	Administrative weight (cost) of the link. Range is 0 to 4294967295.

Command Default

weight : IGP Weight (default OSPF 1, IS-IS 10)

Command Modes

MPLS-TE interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

To use the admin-weight command for MPLS LSP path computations, path-selection metric must be configured to TE.

Task ID


Task ID	Operations
mpls-te	read, write

Examples

The following example shows how to override the IGP cost of the link and sets the cost to 20.


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# mpls traffic-eng
RP/0/RP0/CPU0:router(config-mpls-te)# interface HundredGigE 0/0/0/3
RP/0/RP0/CPU0:router(config-mpls-te-if)# admin-weight 20

affinity

To configure an affinity (attributes which MPLS-TE tunnel requires in its links) for an MPLS-TE tunnel, use the affinity command in interface configuration mode. To disable this behavior, use the no form of this command.

affinity {affinity-value mask mask-value | exclude name | exclude-all | include name | include-strict name | flex-algo name | include-any name }

no affinity { affinity-value mask mask-value | exclude name | exclude-all | include name | include-strict name | include-any name }

Syntax Description


`affinity-value`	Attribute values that are required for links to carry this tunnel. A 32-bit decimal number. Range is from 0x0 to 0xFFFFFFFF, representing 32 attributes (bits), where the value of an attribute is 0 or 1.
mask `mask-value`	Checks the link attribute. A 32-bit decimal number. Range is 0x0 to 0xFFFFFFFF, representing 32 attributes (bits), where the value of an attribute mask is 0 or 1.
exclude `name`	Configures a particular affinity to exclude.
exclude-all	Excludes all affinities.
include `name`	Configures the affinity to include in the loose sense.
include-strict `name`	Configures the affinity to include in the strict sense.
include-any `name`	Configures the affinities to include any of the affinity names.

Command Default

affinity-value : 0X00000000

mask-value : 0x0000FFFF

Command Modes

Interface configuration

Command History


Release	Modification
Release 7.5.4	The include-any keyword was introduced.
Release 7.0.12	This command was introduced.

Usage Guidelines

Affinity determines the link attributes of the tunnel (that is, the attributes for which the tunnel has an affinity). The attribute mask determines which link attribute the router should check. If a bit in the mask is 0, the attribute value of a link or that bit is irrelevant. If a bit in the mask is 1, the attribute value of that link and the required affinity of the tunnel for that bit must match.

A tunnel can use a link if the tunnel affinity equals the link attributes and the tunnel affinity mask.

If there is an affinity failure, a 5-minute timer is started at the LSP headend. If the tunnel is not able to reoptimize within the timeframe, it is torn down. However, if you execute the mpls traffic-eng reoptimize disable affinity-failure command, no timer is started and the tunnel is not torn down. At a subsequent time, other triggers for reoptimization may start the timer for the LSPs with affinity failure.

Any properties set to 1 in the affinity should be 1 in the mask. The affinity and mask should be set as follows:


  tunnel_affinity=tunnel_affinity and tunnel_affinity_mask

You can configure up to 16 affinity constraints under a given tunnel. These constraints are used to configure affinity constraints for the tunnel:

Include constraint: Specifies that a link is considered for Constrained Shortest Path First (CSPF) if it contains all affinities associated with the include constraint. An acceptable link contains more affinity attributes than those associated with the include statement. You can have multiple include statements under a tunnel configuration.
Include-strict constraint: Specifies that a link is considered for CSPF if it contains only the colors associated with the include-strict statement. The link cannot have any additional colors. In addition, a link without a color is rejected.
Exclude constraint: Specifies that a link satisfies an exclude constraint if it does not have all the colors associated with the constraint. In addition, a link that does not have any attribute satisfies an exclude constraint.
Exclude-all constraint: Specifies that only the links without any attribute are considered for CSPF. An exclude-all constraint is not associated with any color; whereas, all other constraint types are associated with up to 10 colors.
Include-any constraint: Specifies that all the links with any attribute are considered for CSPF. An include-all constraint is associated with any color.

You set 1 bit for each color; however, the sample output shows multiple bits at the same time. For example, you can configure red and orange colors on HundredGigabitEthernet 0/0/0/3 from the interface command. The sample output from the show mpls traffic-eng link-management interfaces command shows that the Attributes field is set to 0x21, which means that there are 0x20 and 0x1 bits on the link.

Examples

This example shows how to configure the tunnel affinity and mask:


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# affinity 0101 mask 303

This example shows that a link is eligible for CSPF if the color is red. The link can have any additional colors.


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# affinity include red

This example shows that a link is eligible for CSPF if it has at least red and orange colors. The link can have any additional colors.


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# affinity include red orange

This sample output shows that the include constraint from the show mpls traffic-eng tunnels command is 0x20 and 0x1:

     History:

This example shows that a tunnel can go over a link that contains red or orange affinity. A link is eligible for CSPF if it has a red color or a orange color. Thus, a link with red and any other colors and a link with orange and other additional colors must meet the constraint.


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# affinity include red
RP/0/RP0/CPU0:router(config-if)# affinity include orange

This sample output shows that the include constraint from the show mpls traffic-eng tunnels command is 0x20 or 0x1:

     History:

This example shows that a link is eligible for CSPF if it has only red color. The link must not have any additional colors.


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# affinity include-strict red

Command Modes

MPLS TE configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

The values specified for an attribute within a path-option attribute-set does not prevent the configuration of the same attribute at the tunnel level. However, only one level is taken into consideration. The configuration at the path-option level is considered more specific than the one at the level of the tunnel, and is therefore used.

Attributes that are not specified within an attribute-set picks their default values, as usual, from the configuration at the tunnel level, the configuration at the global mpls level, or default values.

An XRO attribute-set can be specified as part of the path-option, if required. An empty XRO attribute set results in the GMPLS tunnel being signaled with no exclusions, and therefore no XRO.

RP/0/RP0/CPU0:router(config-mpls-te)# auto-bw collect frequency 100

auto-bw (MPLS-TE)

To configure automatic bandwidth on a tunnel interface and to enter MPLS-TE automatic bandwidth interface configuration mode, use the auto-bw command in the interface configuration mode. To remove the automatic bandwidth function, use the no form of this command.

auto-bw [ auto-capacity [ { max-clones | merge-bandwidth | min-clones | nominal-bandwidth | split-bandwidth } value ] ]

no auto-bw [ auto-capacity [ max-clones | merge-bandwidth | min-clones | nominal-bandwidth | split-bandwidth ] ]

Syntax Description


auto-capacity	(Optional) Enables the auto-capacity function for numbered TE tunnels.
max-clones	(Optional) Specifies the maximum number of clone tunnels that the original tunnel can create.
merge-bandwidth	(Optional) Specifies the bandwidth for merging clones with the original tunnel. If the bandwidth goes below the merge bandwidth value, MPLS-TE removes the clone tunnels.
min-clones	(Optional) Specifies the minimum number of clone tunnels that the original tunnel can create.
nominal-bandwidth	(Optional) Specifies the average bandwidth for computing the number of tunnels to satisfy the overall demand.
split-bandwidth	(Optional) Specifies the bandwidth value for splitting the original tunnel. If the tunnel bandwidth exceeds the configured split bandwidth, MPLS-TE creates tunnel clones.
`value`	(Optional) Value of the specified parameter.

Command Default

By default, automatic bandwidth is not enabled.

Command Modes

Interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.
Release 7.10.1	The auto-capacity function was introduced for numbered TE tunnels.

Usage Guidelines

Use the auto-bw command to enter MPLS-TE automatic bandwidth interface configuration mode.

The auto-bw and load-share unequal commands should not be used together.

The load-share unequal command determines the load-share for a tunnel based on the bandwidth. However, the MPLS-TE automatic bandwidth feature changes the bandwidth around. If you are configuring both the load-share unequal command and the MPLS-TE automatic bandwidth feature, it is recommended that you specify an explicit load-share value configuration under each MPLS-TE automatic bandwidth tunnel.

The following automatic bandwidth scenarios are described:

If you configure the automatic bandwidth on a tunnel, the automatic bandwidth is enabled on that tunnel. If no other configuration is specified, defaults for the various parameters are used, the operation stops.
The automatic operation (for example, output rate collection) starts when the automatic bandwidth is enabled on one tunnel. If automatic bandwidth is disabled from all tunnels, the operation stops.

If the output rate collection is already active when the automatic bandwidth is configured on a tunnel, the statistics collection for that tunnel starts at the next collection configuration.

Note

Because the collection timer is already running, the first collection event for that tunnel happens in less than C minutes (for example, on an average of C/2 minutes).

autoroute announce

To specify that the Interior Gateway Protocol (IGP) should use the tunnel (if the tunnel is up) in its enhanced shortest path first (SPF) calculation, use the autoroute announce command in interface configuration mode. To return to the default behavior, use the no form of this command.

autoroute announce [ exclude-traffic segment-routing [ all ] ] [ include-ipv6 ] [ metric value ]

no autoroute announce

Syntax Description


exclude-traffic segment-routing	(Optional) Prevents steering of MPLS labelled Segment Routing (SR) traffic into the MPLS-TE tunnel.
exclude-traffic segment-routing all	(Optional) Prevents steering of segment routing MPLS labelled traffic or IP traffic to destinations associated with a segment routing prefix SID into the MPLS-TE tunnel.
include-ipv6	(Optional) Announces the MPLS-TE tunnel to IS-IS IGP for IPv6 routing.
metric `value`	(Optional) Specify the MPLS-TE tunnel metric that the Interior Gateway Protocol (IGP) enhanced Shortest Path First (SPF) calculation uses.

Syntax Description

This command has no arguments or keywords.

Command Default

Command Modes

Interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.
Release 24.4.1	The new keyword, all, was added to the autoroute announce exclude-traffic segment-routing command.

Usage Guidelines

When more than one IGP is configured, the tunnel is announced as autoroute to the IGP that is used to compute the TE tunnel path.

When the autoroute announce command is configured, the route metric of the tunnel path to the destination equals the route metric of the shortest IGP path to that destination.

The autoroute announce metric configuration overrides the autoroute metric configuration, if present.

Note

IS-IS is the only IGP supporting IPv6 MPLS-TE tunnel announcements.

backup-bw

To configure the backup bandwidth for an MPLS-TE backup tunnel (that is used to protect a physical interface), use the backup-bw command in interface configuration mode. To return to the default behavior, use the no form of this command.

backup-bw {backup bandwidth {any-class-type | class-type ct} | global-pool {bandwidth | unlimited} | sub-pool {bandwidth | unlimited} | unlimited {any-class-type | class-type ct}}

no backup-bw {backup bandwidth {any-class-type | class-type ct} | global-pool {bandwidth | unlimited} | sub-pool {bandwidth | unlimited} | unlimited {any-class-type | class-type ct}}

Syntax Description


`backup` `bandwidth`	Backup bandwidth in any-pool provided by an MPLS-TE backup tunnel. Bandwidth is specified in kilobits per second (kbps). Range is 1 to 4294967295.
any-class-type	Displays the backup bandwidth assigned to any class-type protected tunnels.
class-type ct	Displays the class type of the backup bandwidth. Range is 0 to 1.
global-pool `bandwidth`	(In Prestandard DS-TE with RDM) Displays the backup bandwidth in global pool provided by an MPLS-TE backup tunnel. Bandwidth is specified in kilobits per second. Range is 1 to 4294967295.
unlimited	Displays the unlimited bandwidth.
sub-pool `bandwidth`	(In Prestandard DS-TE with RDM) Displays the backup bandwidth in sub-pool provided by an MPLS-TE backup tunnel. Bandwidth is specified in kilobits per second. Range bandwidth is 1 to 4294967295. Only label switched paths (LSPs) using bandwidth from the sub-pool can use the backup tunnel.

Command Default

Any class-type unlimited.

Command Modes

Interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

Backup bandwidth can be limited or unlimited or specific to a global pool, sub-pool, or non-specific any-pool. Backup with backup-bw in global-pool protects global-pool LSPs only; backup-bw in sub-pool protects sub-pool LSPs only.

Backup tunnels configured with limited backup bandwidth (from any/global/sub pool) are not assigned to protect LSPs configured with zero signaled bandwidth.

Backup bandwidth provides bandwidth protection for fast reroute (FRR). Bandwidth protection for FRR supports DiffServ-TE with two bandwidth pools (class-types).

Class-type 0 is strictly equivalent to global-pool; class-type 1 is strictly equivalent to sub-pool bandwidth using the Russian Doll Model (RDM).

RP/0/RP0/CPU0:router(config-if)# backup-bw global-pool unlimited

or


RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# backup-bw unlimited class-type 0

In the following example, backup tunnel 2 is used by LSPs that take their bandwidth from the sub-pool (class-type 1 tunnels) only. Backup tunnel 2 provides bandwidth protection for up to 1000 units.


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface tunnel-te 2
RP/0/RP0/CPU0:router(config-if)# backup-bw sub-pool 1000

backup-path tunnel-te

To set an MPLS-TE tunnel to protect a physical interface against failure, use the backup-path tunnel-te command in MPLS-TE interface configuration mode. To return to the default behavior, use the no form of this command.

backup-path tunnel-te tunnel-number

no backup-path tunnel-te tunnel-number

Syntax Description


`tunnel-number`	Number of the tunnel protecting the interface. Range is 0 to 65535.

Command Default

No default behavior or values

Command Modes

MPLS-TE interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

When the protected interface is down (shut down or removed), the traffic it was carrying (for the other label switched paths [LSPs], referred to as the protected LSPs) is rerouted, using fast reroute (FRR) onto the backup tunnels.

The following guidelines pertain to the FRR process:

Multiple (backup) tunnels can protect the same interface by entering this command multiple times for different tunnels. The same (backup) tunnel can protect multiple interfaces by entering this command for each interface.
The backup tunnel used to protect a physical interface must have a valid IP address configured.
The backup tunnel cannot pass through the same interface that it is protecting.
TE tunnels that are configured with the FRR option, cannot be used as backup tunnels.
For the backup tunnel to provide protection to the protected LSP, the backup tunnel must have a terminating-end node in the path of a protected LSP.
The source IP address of the backup tunnel and the merge point (MP) address (the terminating-end address of the backup tunnel) must be reachable.

Note

You must configure record-route on TE tunnels that are protected by multiple backup tunnels merging at a single node.

bandwidth-accounting

To enable RSVP-TE bandwidth accounting and dark bandwidth advertisement for all MPLS-TE enabled links, use the bandwidth-accounting command in MPLS-TE configuration mode.

bandwidth-accounting [ adjustment-factor percentage | application-interval seconds | sampling-interval seconds | flooding threshold { up | | down } percentage | flooding sr-traffic percentage ]

Syntax Description

adjustment-factor percentage

Configures TE to over-book (>100%) or under-book (<100%) the effective maximum reservable bandwidth. The measured dark-bandwidth will be scaled based on the adjustment factor. Range is 0 to 200. The default value is 100.

application-interval seconds

Configures the length of the application interval in seconds. At the end of application interval, dark bandwidth rates are computed and applied to all RSVP-TE enabled interfaces. Range is 90 to 1800. The default value is 180.

Note

Model-driven telemetry supports dark bandwidth. The telemetry polling interval is reduced to 10 seconds.

sampling-interval seconds

Configures the length of the sampling interval in seconds. The bandwidth rate is collected from the statistics collector process (statsD) at the end of each sampling interval for each TE link. Range is from 30 to 600. The default is 60.

flooding threshold { up | down} percentage

Configures the reserved bandwidth change percentages threshold. When bandwidth change percentage crosses one of these thresholds, flooding is triggered. Range is from 0 to 100. The default value for up and down is 10.

flooding sr-traffic percentage

Configures the flooding trigger for bandwidth accounting in segment routing traffic. When the bandwidth crosses the threshold value, flooding is triggered. The range is from 0 to 100. The default value is 10.

Command Default

RSVP-TE bandwidth accounting is disabled.

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 7.5.4	The flooding sr-traffic keyword was introduced.
Release 7.0.12	This command was introduced.

Usage Guidelines

If the interval is reconfigured while the timer is running, the new value is compared to the time remaining for the running timer. The timer is adjusted so that the lower of these two values is used for this interval. The subsequent interval will use the newly configured value.

Note

The actual application interval might be different from the configured interval. The actual application interval is rounded based on the number of samples in one application. For example, if the sample interval is 31, and the application interval is 90, then the actual application interval will be rounded to 93.

bw-limit (MPLS-TE)

To configure the minimum and maximum automatic bandwidth to be set on a tunnel, use the bw-limit command in MPLS-TE automatic bandwidth interface configuration mode. To disable this feature, use the no form of this command.

bw-limit min bandwidth { max bandwidth}

no bw-limit

Syntax Description


min `bandwidth`	Configures the minimum automatic bandwidth, in kbps, on a tunnel. The range is from 0 to 4294967295. The default is 0.
max `bandwidth`	Configures the maximum automatic bandwidth, in kbps, on a tunnel. The range is from 0 to 4294967295. The default is 4294967295.

Command Default

min : 0

max : 4294967295

Command Modes

MPLS-TE automatic bandwidth interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

Both the min and max keywords must be configured.

The bw-limit command automatically sets the minimum bandwidth to the default value of 0, or the bw-limit command automatically sets the maximum to the default value of 4294967295 kbps.

If the value of the min keyword is greater than the max keyword, the bw-limit command is rejected. If you configure and modify the minimum or maximum bandwidth while the automatic bandwidth is already running, the next bandwidth application for that tunnel is impacted. For example, if the current tunnel requested bandwidth is 30 Mbps and the minimum bandwidth is modified to 50 Mbps, the next application sets the tunnel bandwidth to 50 Mbps.

collect-bw-only (MPLS-TE)

To configure only the bandwidth collection without adjusting the bandwidth automatically, use the collect-bw-only command in MPLS-TE automatic bandwidth interface configuration mode. To disable this feature, use the no form of this command.

collect-bw-only

no collect-bw-only

Syntax Description

This command has no arguments or keywords.

Command Default

Bandwidth collection is either enabled or disabled.

Command Modes

MPLS-TE automatic bandwidth interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

If you enable the collect-bw-only command while the automatic bandwidth is already running on a tunnel, the bandwidth application is disabled from that moment. Before you enable the actual bandwidth application, you can get the status of the automatic bandwidth behavior.

If you disable the collect-bw-only command on a tunnel from which the automatic bandwidth is already running, the actual bandwidth application takes place on the tunnel at the next application period.

It is also possible to manually activate a bandwidth application regardless of the collect bandwidth only flag that is being specified on a tunnel. To activate the bandwidth application, use the mpls traffic-eng auto-bw apply (MPLS-TE) command in XR EXEC mode.

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

Note

The tunnel destination address must be a unique MPLS-TE router ID; it cannot be an MPLS-TE link address on a node.

For Point-to-Point (P2P) tunnels, the destination command is used as a single-line command.

ds-te bc-model

To enable a specific bandwidth constraint model (Maximum Allocation Model or Russian Doll Model) on the entire label switched router (LSR), use the ds-te bc-model command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.

ds-te bc-model mam

no ds-te bc-model mam

Syntax Description


mam	Enables the Maximum Allocation Model (MAM) bandwidth constraints model.

Command Default

RDM is the default bandwidth constraint model.

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

You can configure both the MAM and RDM bandwidth values on a single interface before swapping to an alternate global MPLS-TE BC model.

If you configure bandwidth constraints without configuring the corresponding bandwidth constraint values, the router uses default bandwidth constraint values.

MAM is not supported in prestandard DS-TE mode. MAM and RDM are supported in IETF DS-TE mode; RDM is supported in prestandard DS-TE mode.

Note

Changing the bandwidth constraints model affects the entire router and may have a major impact on system performance as nonzero-bandwidth tunnels are torn down.

Task ID


Task ID	Operations
mpls-te	read, write

Examples

The following example shows how to enable the MAM bandwidth constraints model:


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# mpls traffic-eng
RP/0/RP0/CPU0:router(config-mpls-te)# ds-te bc-model mam

ds-te mode

To configure standard differentiated-service TE mode (DS-TE), use the ds-te mode command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.

ds-te mode ietf

no ds-te mode ietf

Syntax Description


ietf	Enables IETF standard mode.

Command Default

Prestandard DS-TE is the default differentiated service mode.

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

The following two DS-TE modes are supported:

Prestandard mode
- The Cisco proprietary mechanism for IGPs and RSVP signalling are used and DS-TE does not interoperate with third-party vendor equipment.

IETF mode

Standard defined extensions are used for IGPs and RSVP signalling and DS-TE in this mode interoperates with third-party equipment.
IETF mode supports two bandwidth constraint models: the Russian Doll Model (RDM) and Maximum Allocation Model (MAM).
RDM is the default model.
Router advertises variable-length bandwidth constraints, max-reservable- bandwidth, and unreserved bandwidths in TE-classes.
tunnels must have valid class-type and priority configured as per TE-class map in use; otherwise, tunnels remain down.
TE-class map (a set of tunnel priority and class-type values) is enabled to interpret unreserved bandwidth values advertised in IGP; therefore, TE-class map must be identical on all nodes for TE tunnels to be successfully established

For DS-TE to function properly, DS-TE modes must be configured identically on all MPLS-TE nodes.

If you need to change the DS-TE mode, you must bring down all tunnel interfaces and after the change, you should flood the updated bandwidth values through the network.

Note

Changing the DS-TE mode affects the entire LSR and can have a major impact on system performance when tunnels are torn down.

Task ID


Task ID	Operations
mpls-te	read, write

Examples

The following example shows how to enable IETF standard mode:


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# mpls traffic-eng
RP/0/RP0/CPU0:router(config-mpls-te)# ds-te mode ietf

ds-te te-classes

To enter DS-TE te-class map configuration mode, use the ds-te te-classes command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.

ds-te te-classes te-class te_class_index {class-type class_type_number {priority pri_number} | unused}

no ds-te te-classes te-class te_class_index {class-type class_type_number {priority pri_number} | unused}

Syntax Description


te-class	Configures the te-class map.
`te_class_index`	TE class-map index. Range is 0 to 7.
class-type	Configures the class type.
`class_type_number`	Class type value in the te-class map. Range is 0 to 1.
priority	Configures the TE tunnel priority.
`pri_number`	TE tunnel priority value. Range is 0 to 7.
unused	Marks the TE-class as unused.

Command Default

The following default te-class maps are used in IETF DS-TE mode:


te-class index	class-type	priority
0	0	7
1	1	7
2	UNUSED	—
3	UNUSED	—
4	0	0
5	1	0
6	UNUSED	—
7	UNUSED	—

Note

The default mapping has 4 TE-classes used with 2 class-types and, 4 TE-classes are unused. TE-class map is not used in prestandard DS-TE mode.

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

In IETF DS-TE mode, modified semantic of the unreserved bandwidth TLV is used. Each of the eight available bandwidth values advertised in the IGP corresponds to a TE class. Because IGP advertises only eight bandwidth values, only eight TE-Classes can be supported in a IETF DS-TE network. The TE-Class mapping must be configured the same way on every router in a DS-TE domain. There is, however, no method to automatically detect or enforce this required consistency.

exclude srlg (auto-tunnel backup)

To specify that automatic backup tunnels should avoid Shared Risk Link Groups (SRLGs) of protected interface, use the exclude srlg command in auto-tunnel backup configuration mode. To disable this feature, use the no form of this command.

exclude srlg [preferred]

no exclude srlg [preferred]

Syntax Description


preferred	(Optional) Causes the backup tunnel to avoid SRLGs of its protected interface(s); however, the backup tunnel is created if SRLGs are not avoided.

Command Default

Strict SRLG

Command Modes

Auto-tunnel backup configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

Strict SRLG configuration of this command means that the path computed for the backup tunnel that is automatically created, must not contain any links that are part of the excluded SRLG groups. If such a path cannot be found, the backup tunnel does not come up.

Configuration of the preferred option allows the automatic backup tunnel to come up even if a path that excludes SRLGs can not be found.

Task ID


Task ID	Operation

Examples

In the following example, automatic backup tunnels must avoid SRLGs of the protected interface.


RP/0/RP0/CPU0:router(config)# mpls traffic-eng

RP/0/RP0/CPU0:router(config-mpls-te-if)# auto-tunnel backup
RP/0/RP0/CPU0:router(config-mpls-te-if-auto-backup)#  exclude srlg preferred

fast-reroute

To enable fast-reroute (FRR) protection for an MPLS-TE tunnel, use the fast-reroute command in interface configuration mode. To return to the default behavior, use the no form of this command.

fast-reroute

no fast-reroute

Syntax Description

This command has no arguments or keywords.

Command Default

FRR is disabled.

Command Modes

Interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

When a protected link used by the fast-reroutable label switched path (LSP) fails, the traffic is rerouted to a previously assigned backup tunnel. Configuring FRR on the tunnel informs all the nodes that the LSP is traversing that this LSP desires link/node/bandwidth protection.

You must allow sufficient time after an RSP RP switchover before triggering FRR on standby RSPs RPs to synchronize with the active RSP RP (verified using the show redundancy command). All TE tunnels must be in the recovered state and the database must be in the ready state for all ingress and egress line cards. To verify this information, use the show mpls traffic-eng tunnels and show mpls traffic-eng fast-reroute database commands.

Note

Wait approximately 60 seconds before triggering FRR after verifying the database state.

Task ID


Task ID	Operations

The following example shows how to enable FRR on an MPLS-TE tunnel:


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# fast-reroute

fast-reroute protect

To enable node and bandwidth protection for an MPLS-TE tunnel, use the fast-reroute protect command in interface configuration mode. To return to the default behavior, use the no form of this command.

fast-reroute protect {bandwidth | node}

no fast-reroute protect

Syntax Description


bandwidth	Enables bandwidth protection request.
node	Enables node protection request.

Command Default

FRR is disabled.

Command Modes

RP/0/RP0/CPU0:router(config-if)# fast-reroute protect bandwidth

fast-reroute timers promotion

To configure how often the router considers switching a protected MPLS-TE tunnel to a new backup tunnel if additional backup-bandwidth or a better backup tunnel becomes available, use the fast-reroute timers promotion command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.

fast-reroute timers promotion interval

no fast-reroute timers promotion

Syntax Description


`interval`	Interval, in seconds, between scans to determine if a label switched path (LSP) should use a new, better backup tunnel. Range is 0 to 604800. A value of 0 disables backup tunnel promotions.

Command Default

interval : 300

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

Setting the interval to a low value puts more load on the CPU because it has to scan all protected LSPs more frequently. It is not recommended that the timer be configured below the default value of 300 seconds.

Pacing mechanisms have been implemented to distribute the load on the CPU when backup promotion is active. Because of this, when a large number of protected LSPs are promoted, some delay is noticeable in backup promotion. If the promotion timer is configured to a very low value (depending on the number of protected LSPs) some protected LSPs may never get promoted.

To disable the timer, set the value to zero.

Task ID


Task ID	Operations
mpls-te	read, write

Examples

The following example shows how to specify that LSPs are scanned every 600 seconds (10 minutes) to determine if they should be promoted to a better backup tunnel:


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# mpls traffic-eng
RP/0/RP0/CPU0:router(config-mpls-te)# fast-reroute timers promotion 600

flooding threshold

To set the reserved bandwidth thresholds for a link as a percentage of the total bandwidth change, use the flooding threshold command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.

flooding threshold {up | down} percent

no flooding thresholds {up | down} percent

Syntax Description


up	Configures the upward flooding threshold as a percentage of the total link bandwidth change.
down	Configures the downward flooding threshold as a percentage of the total link bandwidth change.
`percent`	Bandwidth threshold level. Range is 0 to 100 .

Command Default

No default behavior or values.

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

Use the flooding threshold command to set the up and down thresholds as a percentage of the total bandwidth change. If the flooding threshold command is configured, flooding occurs only if the change from the previous flooding is greater than the configured thresholds.

Task ID


Task ID	Operations
mpls-te	read, write

Examples

The following example shows how to set the reserved bandwidth thresholds as a percentage of the total bandwidth change. Flooding occurs only if the change from the previous flooding is greater than the configured thresholds. In this example, the up and down thresholds are configured as 10 percent. That means, if the last flooded bandwidth percentage is 50 percent, then the flooding occurs only if the bandwidth goes below 40 percent, or if the bandwidth goes above 60 percent.


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# mpls traffic-eng
RP/0/RP0/CPU0:router(config-mpls-te)# flooding threshold up 10 down 10

Release 7.0.12	This command was introduced.

Usage Guidelines

If you do not specify a holdtime time value, a delay is introduced with the following results:

When forwarding-adjacency is configured on a tunnel that is up, TE notifies IGP without any additional delay.
When forwarding-adjacency is configured on a tunnel that is down, TE does not notify IGP.
When a tunnel on which forwarding-adjacency has been configured comes up, TE holds the notification to IGP for the period of holdtime (assuming non-zero holdtime). When the holdtime elapses, TE notifies IGP if the tunnel is still up.

The paths that traffic is taking to the destination can be manipulated by adjusting the forwarding adjacency link metric. To do that, use the bandwidth command. The unit of possible bandwidth values is in kbps.

Examples

This example shows how to configure forwarding adjacency with a holdtime value of 60 milliseconds:


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface tunnel-te 888
RP/0/RP0/CPU0:router(config-if)# forwarding-adjacency holdtime 60

This example shows how to announce MPLS-TE tunnel as an IPv6 forwarding adjacency:


RP/0/RP0/CPU0:router#configure
RP/0/RP0/CPU0:router(config)#interface tunnel-te 65534
RP/0/RP0/CPU0:router(config-if)#forwarding-adjacency 
RP/0/RP0/CPU0:router(config-if-tunte-fwdadj)#include-ipv6

index exclude-address

To exclude an address from a tunnel path entry at a specific index, use the index exclude-address command in explicit path configuration mode. To return to the default behavior, use the no form of this command.

index index-id exclude-address{ ipv4 unicast IP address}

no index index-id

Syntax Description


`index-id`	Index number at which the path entry is inserted or modified. Range is 1 to 65535.
ipv4 unicast `IP address`	Excludes the IPv4 unicast address.

Command Default

No default behavior or values

Command Modes

Explicit path configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

You cannot include or exclude addresses from an IP explicit path unless explicitly configured using the exclude-address keyword.

Use the exclude-address keyword only after entering the explicit path configuration mode.

If you use the exclude-address keyword and specify the IP address of a link, the constraint-based routine does not consider that link when it sets up MPLS-TE paths. If the excluded address is a flooded MPLS-TE router ID, the constraint-based shortest path first (SPF) routine does not consider that entire node.

Note

The person who performs the configuration must know the IDs of the routers, as it may not be apparent if the value refers to the link or to the node.

MPLS-TE accepts IP explicit paths composed of all excluded addresses configured using the exclude-address keyword.

Command Default

No default behavior or values

Command Modes

XR EXEC mode

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

The mpls traffic-eng auto-bw apply command can forcefully expire the current application period on a specified tunnel and immediately apply the highest bandwidth recorded so far instead of waiting for the application period to end on its own.

Note

The predefined threshold check still applies on the configuration, and if the delta is not significant enough, the automatic bandwidth functionality overrides this command.

The bandwidth application is performed only if at least one output rate sample has been collected for the current application period.

To guarantee the application of a specific signaled bandwidth value when triggering a manual bandwidth application, follow these steps:

Configure the minimum and maximum automatic bandwidth to the bandwidth value that you want to apply by using the command.
Trigger a manual bandwidth application by using the mpls traffic-eng auto-bw apply command.
Revert the minimum and maximum automatic bandwidth value back to their original value.

Command Modes

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

A routers identifier acts as a stable IP address for the TE configuration. This IP address is flooded to all nodes. You must set the destination on the destination node TE router identifier for all affected tunnels. This router ID is the address that the TE topology database at the tunnel head uses for its path calculation.

Note

When the mpls traffic-eng router-id command is not configured, global router ID is used by MPLS-TE if there is one configured.

We suggest that you configure the mpls traffic-eng router-id command explicitly under the IGP; otherwise, TE uses the default algorithm to pick up the TE router-id, which can be the highest IP address of the loopback interfaces or physical interfaces.

A TE router-id configuration is highly recommended to ensure that the tunnel head-end picks up the correct source address, and the configured static RPF address at the tail-end matches the tunnel source which avoids unexpected traffic drops.

overflow threshold (MPLS-TE)

To configure the tunnel overflow detection, use the overflow threshold command in MPLS-TE automatic bandwidth interface configuration mode. To disable the overflow detection feature, use the no form of this command.

overflow threshold percentage [min bandwidth] limit limit

no overflow threshold

Syntax Description


`percentage`	Bandwidth change percent to trigger an overflow. The range is from 1 to 100.
min `bandwidth`	(Optional) Configures the bandwidth change value, in kbps, to trigger an overflow. The range is from 10 to 4294967295. The default is 10.
limit `limit`	Configures the number of consecutive collection intervals that exceeds the threshold. The bandwidth overflow triggers an early tunnel bandwidth update. The range is from 1 to 10. The default is none.

Command Default

The default value is disabled.

Command Modes

MPLS-TE automatic bandwidth interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

If you modify the limit keyword, the consecutive overflows counter for the tunnel is also reset.

If you enable or modify the minimum value, the current consecutive overflows counter for the tunnel is also reset, which effectively restarts the overflow detection from scratch.

Several number of consecutive bandwidth samples are greater than the overflow threshold (bandwidth percentage) and the minimum bandwidth configured, then a bandwidth application is updated immediately instead of waiting for the end of the application period.

Overflow detection applies only to bandwidth increase. For example, an overflow can not be triggered even if bandwidth decreases by more than the configured overflow threshold.

Command Default

No default behavior or values

Command Modes

Tunnel-te interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

You can configure several path options for a single tunnel. For example, there can be several explicit path options and a dynamic option for one tunnel. The path setup preference is for lower (not higher) numbers, so option 1 is preferred.

When the lower number path option fails, the next path option is used to set up a tunnel automatically (unless using the lockdown option).

The protecting keyword specifies that you can configure path-protection for the primary LSP. The protecting keyword is available only for tunnel-gte interfaces.

You specify the backup path for the path-option command in case of the primary path failure.

CSPF areas are configured on a per-path-option basis.

The dynamic keyword is required to configure path-protection.

Any primary explicit path on a path protection enabled tunnel can be configured to be protected by an explicit path option level using protected-by keyword. Only one explicit protecting path is supported per path option.

path-selection ignore overload (MPLS-TE)

To ignore the Intermediate System-to-Intermediate System (IS-IS) overload bit setting for MPLS-TE, use the path-selection ignore overload command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.

path-selection ignore overload {head | mid | tail}

no path-selection ignore overload {head | mid | tail}

Syntax Description

This command has no arguments or keywords.

Syntax Description


head	The tunnel stays up if set-overload-bit is set by ISIS on the head router. Ignores overload node during CSPF for the head node.
mid	The tunnel stays up if set-overload-bit is set by ISIS on the mid router. Ignores overload node during CSPF for the mid node.
tail	The tunnel stays up if set-overload-bit is set by ISIS on the tail router. Ignores overload node during CSPF for the tail node.

Command Default

None

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

Use the path-selection ignore overload command to ensure that label switched paths (LSPs) are not broken because of routers that have IS-IS overload bit as enabled.

When the IS-IS overload bit avoidance (OLA) feature is activated, all nodes with the overload bit set, which includes head nodes, mid nodes, and tail nodes, are ignored. This means that they are still available for use with label switched paths (LSPs). This feature allows you to include an overloaded node in constraint-based shortest path first (CSPF).

priority (MPLS-TE)

To configure the setup and reservation priority for an MPLS-TE tunnel, use the priority command in interface configuration mode. To return to the default behavior, use the no form of this command.

priority setup-priority hold-priority

no priority setup-priority hold-priority

Syntax Description


`setup-priority`	Priority used when signaling a label switched path (LSP) for this tunnel to determine which existing tunnels can be preempted. Range is 0 to 7 (in which a lower number indicates a higher priority). Therefore, an LSP with a setup priority of 0 can preempt any LSP with a non-0 priority.
`hold-priority`	Priority associated with an LSP for this tunnel to determine if it should be preempted by other LSPs that are being signaled. Range is 0 to 7 (in which a lower number indicates a higher priority).

Command Default

setup-priority : 7

hold-priority : 7

Command Modes

Interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

When an LSP is signaled and an interface does not currently have enough bandwidth available for that LSP, the call admission software (if necessary) preempts lower-priority LSPs to admit the new LSP. Accordingly, the new LSP priority is the setup priority and the existing LSP priority is the hold priority. The two priorities make it possible to signal an LSP with a low setup priority (so that the LSP does not preempt other LSPs on setup) and a high hold priority (so that the LSP is not preempted after it is established). Setup priority and hold priority are typically configured to be equal, and setup priority cannot be numerically smaller than the hold priority.

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

A device with Multiprotocol Label Switching traffic engineering (MPLS-TE) tunnels periodically examines tunnels with established LSPs to discover whether more efficient LSPs (paths) are available. If a better LSP is available, the device signals the more efficient LSP; if the signaling is successful, the device replaces the older LSP with the new, more efficient LSP.

Sometimes the slower router-point nodes may not yet utilize the new label’s forwarding plane. In this case, if the headend node replaces the labels quickly, it can result in brief packet loss. By delaying the cleanup of the old LSP using the reoptimize timers delay cleanup command, packet loss is avoided.

RP/0/RP0/CPU0:router(config)# mpls traffic-eng
RP/0/RP0/CPU0:router(config-mpls-te)# reoptimize timers delay after-frr 50

The following example shows how to set the reoptimization delay time between path protection switchover event and tunnel reoptimization to 80:

RP/0/RP0/CPU0:router(config-mpls-te)# reoptimize timers delay path-protection 80

route-priority

To enable users to adjust the route-priority given to TE labels into the data plane, compared to labels and route updates from other protocols, use the route-priority command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.

route-priority role {middle | head {primary | backup}} queue queue

no route-priority role {middle | head {primary | backup}}

Syntax Description


role	Defines the role of the tunnel to which the label belongs.
middle	A tunnel mid-point.
head backup	A tunnel head which is assigned as a FRR backup to an interface.
head primary	All other tunnel heads.

head primary: 10

middle: 10

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

Use this command to change the priority given to TE labels when updates to the forwarding plane are made from the control plane.

The priority values used by other applications are:

0 - Unused
1 - Unused
2 - RIB/LDP (Critical)
3 - Unused
4 - Unused
5 - RIB/LDP (High)
6 - Unused
7 - Unused
8 - RIB/LDP (Medium)
9 - TE backup tunnel head
10 - Other TE tunnels
11 - Unused (future TE use)
12 - Unused (future TE use)

Caution

The default prioritization of label updates from the control plane to the forwarding plane has been carefully chosen to avoid traffic loss under both normal operation and high system load, and to balance the needs of the various features that employ label switching. Changing these defaults may cause unpredictable behavior including traffic loss, especially when the router is experiencing high load. Use of this command is not recommended without proper understanding of its effects and possible side-effects.

Note

This attribute-set is an optional configuration. Without this configuration, all tunnels use default tunnel attribute values. If you configure an non-existent attribute-set, this mesh group does not create any tunnel.

Note

This destination-list configuration is mandatory. If there is no IPv4 prefix-list by this name on the router, this mesh group create tunnels with all routers in the network.

Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

The traffic-engineering tunnels are taken into account for the enhanced shortest path first (SPF) calculation of the IGP. The show mpls traffic-eng autoroute command displays those tunnels that IGP is currently using in its enhanced SPF calculation (that is, those tunnels that are up and have autoroute configured).

Tunnels are organized by destination. All tunnels to a destination carry a share of the traffic tunneled to that destination.

This table describes the significant fields shown in the display.

Table 3. show mpls traffic-eng autoroute Command Field Descriptions
Field	Description
Destination	Multiprotocol Label Switching (MPLS) TE tail-end router ID.
traffic share	A factor, based on bandwidth, indicating how much traffic this tunnel should carry, relative to other tunnels, to the same destination. If two tunnels go to a single destination, one with a traffic share of 200 and the other with a traffic share of 100, the first tunnel carries two-thirds of the traffic.
Nexthop	Next-hop router ID of the MPLS-TE tunnel.
absolute metric	Metric with mode absolute for the MPLS-TE tunnel.
relative metric	Metric with mode relative for the MPLS-TE tunnel.

This sample output displays Signalled-Name information:

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

Use the brief form of the show mpls traffic-eng tunnels command to display information specific to a tunnel interface. Use the command without the brief keyword to display information that includes the destination address, source ID, role, name, suboptimal constraints, and interface.

The affinity keyword is available for only the source router.

Selected tunnels would have a shorter path if they were reoptimized immediately.

To display the path-protection summary fields, you must configure the options for the path-protection.

Examples

This sample output is not changed when no area is specified for the active path-option. If the area is specified, it is added on a line of its own after the existing path-option information.

Field

Description

Auto Backup

Auto backup section header.

Creation Time

Time when the tunnel was created and for what period was the tunnel created.

Protected LSPs

Number of ready and active LSPs protected by this backup.

Protected S2L Sharing Familes

Number of ready and active sharing families protected by this backup.

Protected S2Ls

Number of ready and active primary tunnels protected by this backup.

Protected i/f

Protected node

signalled-bandwidth

To configure the bandwidth required for an MPLS-TE tunnel, use the signalled-bandwidth command in interface configuration mode. To disable the behavior, use the no form of this command.

signalled-bandwidth {bandwidth [class-type ct] | sub-pool bandwidth}

no signalled-bandwidth {bandwidth [class-type ct] | sub-pool bandwidth}

Syntax Description


`bandwidth`	Bandwidth required for an MPLS-TE tunnel. Bandwidth is specified in kilobits per second. By default, bandwidth is reserved in the global pool. Range is from 0 to 4294967295.
class-type `ct`	(Optional) Configures the class type of the tunnel bandwidth request. Range is from 0 to 1. Class-type 0 is strictly equivalent to global-pool. Class-type 1 is strictly equivalent to subpool.
sub-pool `bandwidth`	Reserves the bandwidth in the subpool instead of the global pool. Range is 1 to 4294967295. A subpool bandwidth value of 0 is not allowed.

Command Default

The default is 0 in class-type 0.

Command Modes

Interface configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

The signalled-bandwidth command supports two bandwidth pools (class-types) for the Diff-Serv Aware TE (DS-TE) feature. This command is also used as the bandwidth startup value to bring up the auto bandwidth enabled tunnels.

Note

The Cisco Diff-Serve Aware TE feature is compliant to IETF standard and will interoperate with third party vendor DS-TE. Both Russian Doll Model and Maximum Allocation Model for bandwidth allocation are supported. We recommended that IETF terminology be used in DS-TE bandwidth configurations, namely, Class-type (CT) and Bandwidth Constraints (BC).

Examples

This example shows how to set the bandwidth required for an MPLS-TE tunnel to 1000 in the global pool (class-type 0):


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# signalled-bandwidth 1000
  
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# signalled-bandwidth 1000 class-type 0

This example shows how to set the bandwidth required for an MPLS-TE tunnel to 1000 in the sub-pool (class-type 1):


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# signalled-bandwidth sub-pool 1000
  
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1
RP/0/RP0/CPU0:router(config-if)# signalled-bandwidth 1000 class-type 1

signalled-name

To configure the name of the tunnel required for an MPLS-TE tunnel, use the signalled-name command in interface configuration mode. To return to the default behavior, use the no form of this command.

signalled-name name

no signalled-bandwidth name

Syntax Description


`name`	Name used to signal the tunnel.

Command Default

Default name is the hostname_tID, where ID is the tunnel interface number.

Command Modes

snmp traps mpls traffic-eng

To enable the router to send Multiprotocol Label Switching traffic engineering (MPLS-TE) Simple Network Management Protocol (SNMP) notifications or informs, use the snmp traps mpls traffic-eng command in XR Config mode. To disable this behavior, use the no form of this command.

snmp traps mpls traffic-eng [notification-option] preempt

no snmp traps mpls traffic-eng [notification-option]

Syntax Description


`notification-option`	(Optional) Notification option to enable the sending of notifications to indicate changes in the status of MPLS-TE tunnels. Use one of these values: up down reoptimize reroute cisco-ext
preempt	Enables MPLS-TE tunnel preempt trap.

Command Default

None

Command Modes

XR Config mode

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

If the command is entered without the notification-option argument, all MPLS-TE notification types are enabled.

SNMP notifications can be sent as either traps or inform requests.

The snmp-server enable traps mpls traffic-eng command enables both traps and inform requests for the specified notification types. To specify whether the notifications should be sent as traps or informs, use the snmp-server host command and specify the keyword trap or informs .

If you do not enter the snmp traps mpls traffic-eng command, no MPLS-TE notifications controlled by this command are sent. To configure the router to send these MPLS-TE SNMP notifications, you must enter at least one snmp enable traps mpls traffic-eng command. If you enter the command with no keywords, all MPLS-TE notification types are enabled. If you enter the command with a keyword, only the notification type related to that keyword is enabled. To enable multiple types of MPLS-TE notifications, you must issue a separate snmp traps mpls traffic-eng command for each notification type and notification option.

The snmp traps mpls traffic-eng command is used in conjunction with the snmp host command. Use the snmp host command to specify which host or hosts receive MPLS-TE SNMP notifications. To send notifications, you must configure at least one snmp host command.

For a host to receive an MPLS-TE notification controlled by this command, both the snmp traps mpls traffic-eng command and the snmp host command for that host must be enabled.

Command Default

seconds : 10

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced

Usage Guidelines

A router at the headend for TE tunnels can receive a Resource Reservation Protocol (RSVP) No Route error message before the router receives a topology update from the IGP routing protocol announcing that the link is down. When this happens, the headend router ignores the link in subsequent tunnel path calculations to avoid generating paths that include the link and are likely to fail when signaled. The link is ignored until the router receives a topology update from its IGP or a link holddown timeout occurs. Use the topology holddown sigerr command to change the link holddown time from its 10-second default value.

Task ID


Task ID	Operations
mpls-te	read, write

Examples

The following example shows how to set the link holddown time for signaling errors at 15 seconds:


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# mpls traffic-eng 
RP/0/RP0/CPU0:router(config-mpls-te)# topology holddown sigerr 15

tunnel-id (auto-tunnel backup)

To configure the range of tunnel interface numbers to be used for automatic backup tunnels, use the tunnel-id command in auto-tunnel backup configuration mode. To delete the automatic backup tunnels, use the no form of this command.

max	(Optional) Maximum number for automatic backup tunnels.

Command Default

No default behavior or values

Command Modes

Auto-tunnel backup configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced

Usage Guidelines

If you increase the tunnel ID range, the automatic backup tunnels that failed earlier will get created the next time automatic backup assignments are processed.

Restrictions:

Command is rejected if the max value minusmin value is >= 1K.
Command is rejected if min value > max value .
Command is rejected if min value is greater than the tunnel ID of an existing automatic backup tunnel.
Command is rejected if max value is smaller than the tunnel ID of an existing automatic backup tunnel.
Command is rejected if a statically configured tunnel ID matches with the configured min and max range of values .
Command is rejected if a static backup assignment is already configured to a tunnel with an ID within the min value /max value range.

Task ID


Task ID	Operation
