RP/0/RP0/CPU0:router# clear mpls forwarding counters

mpls ip-ttl-propagate

To configure the behavior controlling the propagation of the IP Time-To-Live (TTL) field to and from the MPLS header, use the mpls ip-ttl-propagate command in XR Config mode. To return to the default behavior, use the no form of this command.

mpls ip-ttl-propagate disable [forwarded | local]

no mpls ip-ttl-propagate

Syntax Description

disable

Disables the propagation of IP TTL to and from the MPLS header for both forwarded and local packets.

forwarded

(Optional) Disables the propagation of IP TTL to and from the MPLS headed for only the forwarded packets. This prevents the traceroute command from displaying the MPLS-enabled nodes beyond the device under the configuration.

local

(Optional) Disables the propagation of IP TTL to the MPLS header for only locally generated packets. This prevents the traceroute command from displaying the MPLS-enabled nodes beyond the device under the configuration.

Command Default

Enabled

Command Modes

XR Config mode

Command History

Release

Modification

Release 6.0

This command was introduced.

Usage Guidelines

By default, the IP TTL is propagated to the MPLS header when IP packets enter the MPLS domain. Within the MPLS domain, the MPLS TTL is decremented at each MPLS hop. When an MPLS encapsulated IP packet exits the MPLS domain, the MPLS TTL is propagated to the IP header. When propagation is disabled, the MPLS TTL is set to 255 during the label imposition phase and the IP TTL is not altered.

The following example shows how to disable IP TTL propagation for forwarded MPLS packets: 


RP/0/RP0/CPU0:router(config)# mpls ip-ttl-propagate disable forwarded

The following example shows how to disable IP TTL propagation for locally generated MPLS packets: 


RP/0/RP0/CPU0:router(config)# mpls ip-ttl-propagate disable local

mpls label range

To configure the dynamic range of local labels available for use on packet interfaces, use the mpls label range command in XR Config mode. To return to the default behavior, use the no form of this command.

mpls label range table table-id minimum maximum

no mpls label range table table-id minimum maximum

Syntax Description

table table-id

Identifies a specific label table; the global label table has table-id = 0. If no table is specified, the global table is assumed. Currently, you can specify table 0 only.

minimum

Smallest allowed label in the label space. Default is 16000.

maximum

Largest allowed label in the label space. Default is 1048575.

Command Default

table-id : 0

minimum : 16000

maximum : 1048575

Command Modes

XR Config mode

Command History

Release

Modification

Release 6.0

This command was introduced.

Usage Guidelines

After configuring the mpls label range command, restart the router for the configuration to take effect.

The label range defined by the mpls label range command is used by all MPLS applications that allocate local labels (for dynamic label switching Label Distribution Protocol [LDP], MPLS traffic engineering, and so on).

Labels 0 through 15 are reserved by the Internet Engineering Task Force (IETF) (see the RFC 3032 reference for details)and cannot be included in the range using the mpls label range command.

The maximum allowed label limit is 1000000 when Enhanced Ethernet Line Card is used.


Note

  • Labels outside the current range and which are allocated by MPLS applications remain in circulation until released.

  • The maximum labels that are available are 144K.

mpls label-security

To configure the MPLS label security for the interface, use the mpls label-security command in interface configuration mode.

mpls label-security multi-label-packet [drop] rpf

show mpls forwarding

To display the contents of the MPLS Label Forwarding Information Base (LFIB), use the show mpls forwarding command in XR EXEC mode.

show mpls forwarding [detail] [hardware {ingress | egress}] [interface type interface-path-id] [location node-id] [labels low-value [high-value] ] [prefix {network/ mask | ipv4 unicast network/ mask} ] [private] [summary] [tunnels tunnel-id] [vrf vrf-name]

Syntax Description

detail

(Optional) Displays information in long form (includes length of encapsulation, length of Media Access Control [MAC] string, maximum transmission unit [MTU], Packet switched, and label stack).

hardware

(Optional) Displays the hardware location entry.

ingress

(Optional) Reads information from the ingress PSE.

egress

(Optional) Reads information from the egress PSE.

interface

(Optional) Displays information for the specified interface.

type

Interface type. For more information, use the question mark (?) online help function.

interface-path-id

Physical interface or a virtual interface.

Note 

Use the show interfaces command to see a list of all possible interfaces currently configured on the router.

For more information about the syntax for the router, use the question mark (?) online help function.

labels low-value [high-value ]

(Optional) Entries with a local labels range. Ranges for both low-value and high-value are 0 to 1048575.

location node-id

(Optional) Displays hardware resource counters on the designated node.

prefix network/ mask / length

(Optional) Displays the destination address and mask/prefix length.

Note 

The forward slash (/) between network and mask is required.

ipv4 unicast

(Optional) Displays the IPv4 unicast address.

private

(Optional) Displays private information.

summary

(Optional) Displays summarized information.

tunnels tunnel-id

(Optional) Displays entries either for a specified label switch path (LSP) tunnel or all LSP tunnel entries.

vrf vrf-name

(Optional) Displays entries for VPN routing and forwarding (VRF).

Command Modes

XR EXEC mode

Command History

Release

Modification

Release 6.0

This command was introduced.

Usage Guidelines

The optional keywords and arguments described allow specification of a subset of the entire MPLS forwarding table.


Note
This router does not support label accounting for vrf labels. Instead, it supports accounting for the IGP and LDP labels. As a result, the Bytes Switched counter is 0 for the show mpls forwarding vrf command.

Note
When the show mpls forwarding detail command is executed with the location keyword (for example, with the address, 0/1/cpu0), it displays the forwarding information available on this node. If this node hosts a displayed interface, then the FIB displays a configured MTU; otherwise, it displays the default value of 1500. This is because in Cisco IOS XR software, interface information is available only on nodes hosting the interface. Note that for bundle interfaces, the information is available in line cards with bundle-member links. If the location is not specified, the FIB displays the data from the node where the interface is created. For physical interfaces, this location keyword value would match the actual address; therefore, FIB displays correct information. It is different in the case of bundles--bundles are created on RP, but located on LC(s); therefore, you would see default values. This is also applicable to any per-interface data; for example, adjacencies.

The node-id argument is entered in the rack/slot/module notation.
