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.
