mpls te link administrative group name

Function

The mpls te link administrative group name command allows you to specify bit names for a link administrative group on an interface.

The undo mpls te link administrative group name command deletes the link administrative group names.

By default, a link administrative group is 0x0, and no bit names are specified for it.

Format

mpls te link administrative group name { bit-name } &<1-32>

undo mpls te link administrative group name { bit-name } &<1-32>

undo mpls te link administrative group name

Parameters

Parameter	Description	Value
bit-name	Specifies names of link administrative group bits. A node compares an affinity with a link administrative group to determine whether a path passes though links with specified attributes.	The value is a string of 1 to 31 case-sensitive characters.

Usage Guidelines

Usage Scenario

A link administrative group is a 128-bit vector representing a link attribute. Currently, a name can be configured for a link administrative group. When a device establishes an MPLS TE tunnel, it uses the link administrative group and affinity attributes together to determine the link used by the tunnel.

Prerequisites

MPLS TE has been enabled on the interface using the mpls te command.
Mappings between names and bit values in an affinity have been configured using the attribute command.

Configuration Impact

Changed link administrative group configurations take effect on new LSPs, not on existing LSPs.

Precautions

The mpls te link administrative group name command is run on the outbound interface of a link through which a TE tunnel passes.

Example

# Set bit names for a link administrative group to yellow and brown.
