MPLS Command Reference for Cisco NCS 6000 Series Routers

adjustment-threshold (MPLS-TE)

To configure the tunnel bandwidth change 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]

Syntax Description


`percentage`	Bandwidth change 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

Command Modes

MPLS-TE automatic bandwidth interface configuration

Command History


Release	Modification
Release 5.0.0	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 change 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

Related Commands


Command	Description
application (MPLS-TE)	Configures the application frequency, in minutes, for the applicable tunnel.
auto-bw (MPLS-TE)	Configures automatic bandwidth on a tunnel interface and enters MPLS-TE automatic bandwidth interface configuration mode.
bw-limit (MPLS-TE)	Configures the minimum and maximum automatic bandwidth to set on a tunnel.
collect-bw-only (MPLS-TE)	Enables only the bandwidth collection without adjusting the automatic bandwidth.
overflow threshold (MPLS-TE)	Configures tunnel overflow detection.
show mpls traffic-eng tunnels	Displays information about MPLS-TE tunnels.

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

Syntax Description


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

Command Default

weight : IGP Weight (default OSPF 1, ISIS 10)

Command Modes

path-selection metric (interface)	Specifies an MPLS-TE tunnel path-selection metric type.

affinity

To configure an affinity (the properties the 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 | ignore | include name | include-strict 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.
ignore	Ignore affinity attributes.
include `name`	Configures the affinity to include in the loose sense.
include-strict `name`	Configures the affinity to include in the strict sense.

Command Default

affinity-value : 0X00000000

mask-value : 0x0000FFFF

Interface configuration

Command History


Release	Modification
Release 5.0.0	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.

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: 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: 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: 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: 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.
Ignore: Ignores affinity attributes while considering links for CSPF.

You set one 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 GigabitEthernet0/4/1/3 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 example shows how to configure a tunnel to ignore the affinity attributes on links.


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

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


Name: tunnel-te1 Destination: 0.0.0.0
     Status:
       Admin:    up Oper: down   Path: not valid   Signalling: Down

     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:


Name: tunnel-te1 Destination: 0.0.0.0
     Status:
       Admin:    up Oper: down   Path: not valid   Signalling: Down

     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

This example shows that a link is eligible for CSPF if it does not have the red attribute:


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

This example shows that a link is eligible for CSPF if it does not have red and blue attributes. Thus, a link that has only a red attribute or only a blue attribute is eligible for CSPF.


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

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 MPLS-TE interface configuration mode. To disable the automatic bandwidth on that tunnel, use the no form of this command.

auto-bw

Syntax Description

This command has no arguments or keywords.

Command Default

By default, automatic bandwidth is not enabled.

Command Modes

MPLS-TE interface configuration

Command History


Release	Modification
Release 5.0.0	This command was introduced.

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, we recommend 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 as soon as 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).

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}}

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 5.0.0	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).

Commands	Description
backup-path tunnel-te	Assigns one or more backup tunnels to a protected interface.
fast-reroute	Enables FRR protection for an MPLS-TE tunnel.
interface tunnel-te	Configures an MPLS-TE tunnel interface.

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

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 5.0.0	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.

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}

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 5.0.0	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.

Release 5.0.0	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.

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 5.0.0	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.

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}

Syntax Description


te-class	Configures the te-class map.
`te_class_index`	TE class-map index. Range is 0 to 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 5.0.0	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.

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

Syntax Description

This command has no arguments or keywords.

Command Default

FRR is disabled.

Command Modes

Interface configuration

Command History


Release	Modification
Release 5.0.0	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 switchover before triggering FRR on standby to synchronize with the active (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.

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

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 5.0.0	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

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

flooding thresholds

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

forwarding-adjacency

To configure an MPLS-TE forwarding adjacency, use the forwarding-adjacency command in interface configuration mode. By configuring forwarding adjacency, the MPLS-TE tunnels are considered to be links by the IGP. If no forwarding adjacency is to be defined, use the no form of this command.

forwarding-adjacency [ holdtime time ]

Syntax Description


holdtime `time`	(Optional) Configures the hold time value, in milliseconds, that is associated with each forwarding-adjacency LSP. The hold time is the duration after which the state change of LSP is advertised to IGP. The default value is 0.

Command Default

holdtime time : 0

Command Modes

Interface configuration

Command History


Release	Modification
Release 5.0.0	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.

Task ID

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}

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 5.0.0	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.

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 bw-limit (MPLS-TE) command.

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 5.0.0	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

None

Command Modes

P2MP destination interface configuration

Command History


Release	Modification
Release 5.0.0	This command was introduced.

Usage Guidelines

You can configure several path options for each destination of a P2MP tunnel. For example, for one tunnel, there can be several explicit path options and a dynamic option. The path preference is for lower (not higher) numbers, so option 1 is preferred over higher options.

When the lower number path option fails, the next path option under the destination is attempted.

Several path-options can be configured for each destination under a tunnel.

When configuring multiple path-options under each destination of a P2MP tunnel, the PCALC on the TE tunnel source attempts to generate the P2MP tree starting from the preferred path-options (lower numbers) for each destination. If some destinations use explicit paths that cause remerges with the dynamic generated paths for other destinations in the P2MP tree, the PCALC source modifies the dynamic paths (for example, optimal path); therefore, it follows the explicit path to correct the remerge problem.

The path-option command is common for both Point-to-Point (P2P) and P2MP tunnels.

Task ID


Task ID	Operations
mpls-te	read, write

Examples

This example shows how to configure a P2MP tunnel with two destinations and several path-options per destination:

RP/0/RP0/CPU0:router(config-if-p2mp-dest)# path-option 1 explicit name po_dest1
RP/0/RP0/CPU0:router(config-if-p2mp-dest)# path-option 2 dynamic

This example shows that the fallback path option is dynamic:


RP/0/RP0/CPU0:router(config)# interface tunnel-mte 100 
RP/0/RP0/CPU0:router(config-if)# destination 172.16.0.1
RP/0/RP0/CPU0:router(config-if-p2mp-dest)# path-option 1 explicit name po_dest2

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 5.0.0	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.

reoptimize timers delay (MPLS-TE)

To delay removal or relabeling of the old label switched paths (LSPs) (reoptimized LSP from the forwarding plane) after tunnel reoptimization, use the reoptimize timers delay command in MPLS-TE configuration mode. To restore the default value, use the no form of this command.

reoptimize timers delay {after-frr seconds | cleanup delay-time | installation delay-time | path-protection seconds}

Syntax Description


after-frr	Delays the LSP reoptimization in the event of the FRR.
`seconds`	Reoptimization initiation delay time of the tunnel, in seconds, after an FRR event. Range is from 0 to 120.
cleanup	Delays removal of the old LSPs after tunnel reoptimization.
`delay-time`	Reoptimization delay time, in seconds. A value of 0 disables delay. The valid range is from 0 to 300 for cleanup time.
installation	Delays installation of a new label after tunnel reoptimization.
`delay-time`	Reoptimization delay time, in seconds. A value of 0 disables delay. The valid range is 0 to 3600 for installation time.
path-protection	Delays the time between path protection switchover event and tunnel reoptimization.
`seconds`	Time, in seconds, between path protection switchover event and tunnel reoptimization. A value of 0 disables delay. Range is from 0 to 604800.

Command Default

after-frr delay : 0

cleanup delay : 20

delay-time : 20

installation delay : 20

path-protection : 180

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 5.0.0	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.

Related Commands


Command	Description
affinity	Configures an affinity (the properties the tunnel requires in its links) for an MPLS-TE tunnel.
affinity-map	Assigns a numerical value to each affinity name.

show mpls traffic-eng autoroute

To display tunnels that are announced to the Interior Gateway Protocol (IGP), including information about next hop and destinations, use the show mpls traffic-eng autoroute command in XR EXEC mode.

show mpls traffic-eng autoroute [IP-address]

Syntax Description


`IP-address`	(Optional) Tunnel leading to this address.

Command Default

None

Command Modes

XR EXEC

Command History


Release	Modification
Release 5.0.0	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.

Task ID


Task ID	Operations
mpls-te	read

Examples

The following shows a sample output from the show mpls traffic-eng autoroute command:


RP/0/RP0/CPU0:router# show mpls traffic-eng autoroute
  
  Destination 103.0.0.3 has 2 tunnels in OSPF 0 area 0
  tunnel-te1 (traffic share 1, nexthop 103.0.0.3)
  tunnel-te2 (traffic share 1, nexthop 103.0.0.3)

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.

Related Commands


Command	Description
autoroute metric	Specifies the MPLS-TE tunnel metric that the IGP-enhanced SPF calculation uses.
show mpls traffic-eng tunnels	Displays information about MPLS-TE tunnels.
topology holddown sigerr (MPLS-TE)	Specifies the time that a router should ignore a link in its TE topology database in tunnel path CSPF computations following a TE tunnel signalling error on the link.

show mpls traffic-eng collaborator-timers

To display the current status of the MPLS-TE collaborator timers, use the show mpls traffic-eng collaborator-timers command in XR EXEC mode.

Release	Modification
Release 5.0.0	This command was introduced.
Release 5.1.2	These changes were made to support the path-selection cost-limit feature: The command output was modified to show the configured cost-limit. The shown PCALC error was modified to show cost-limit failure: applies for new paths and verification of existing paths. The 'Reopt Reason' field in the show output was modified to show the cost-limit. The path-protection switchover reason in the show output was modified to show the cost-limit. The command output was modified to display the 'Traffic switched to FRR backup tunnel-te' message as part of Soft-preemption over FRR backup tunnels feature implementation.

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.

Command Default

Implicit-null labels are advertised.

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 5.0.0	This command was introduced.

Usage Guidelines

Use the signalling advertise explicit-null command to specify that tunnels terminating on this router use explicit-null labels. This command applies to tunnel labels advertised to next to last (penultimate) hop.

The explicit label is used to carry quality-of-service (QoS) information up to the terminating-end router of the label switched path (LSP).

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

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

Command Default

None

Command Modes

Command History


Release	Modification
Release 5.0.0	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.

topology holddown sigerr (MPLS-TE)

To specify the time that a router should ignore a link in its TE topology database in tunnel path constrained shortest path first (CSPF) computations following a TE tunnel signaling error on the link, use the topology holddown sigerr command in MPLS-TE configuration mode. To return to the default behavior, use the no form of this command.

topology holddown sigerr seconds

Syntax Description


`seconds`	Time that the router ignores a link during tunnel path calculations, following a TE tunnel error on the link, specified in seconds. Range is 0 to 300. Default is 10.

Command Default

seconds : 10

Command Modes

MPLS-TE configuration

Command History


Release	Modification
Release 5.0.0	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
