te link administrative group name

Function

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

The undo 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

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

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

undo 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 identifying a link attribute. The device allows you to specify bit names for a link administrative group. When a device establishes an TE tunnel, it compares an affinity with a link administrative group to determine links over which the TE tunnel is established.

Configuration Impact

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

Precautions

The te link administrative group name command needs to be run only on the outbound interface of a link through which a TE tunnel passes.

MPLS TE-related commands apply only to MPLS TE and SR-MPLS TE. However, this command applies to SRv6 TE Policies, besides MPLS TE and SR-MPLS TE.

Example

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