peer virtual-link te link administrative group

Function

The peer virtual-link te link administrative group command configures an affinity value for a virtual link.

The undo peer virtual-link te link administrative group command deletes the affinity value of a virtual link.

The peer virtual-link te link administrative group name command configures an affinity name for a virtual link.

The undo peer virtual-link te link administrative group name command deletes the affinity name configured for a virtual link.

By default, no affinity is configured for a virtual link.

Usage Guidelines

Usage Scenario

A link administrative group is a 32-bit vector representing a virtual link attribute of a BGP neighbor. When configuring peer virtual-link te link administrative group, you need to use the link administrative group attribute and affinity attribute together.

Prerequisites

An affinity name mapping template has been created using the path-constraint affinity-mapping command, and the mapping between affinity names and bits in affinity values has been configured.
A virtual link across an L3 network has been constructed using the peer virtual-link command. Topology information is reported to the controller based on the virtual link for path computation.
