■

Both ends of a virtual link must be ABRs configured with the vlink-peer 
command.

■

A virtual link cannot transit the backbone area.

■

The vlink-peer command needs to be used in the transit area.

When advertising, redistributing or receiving routing information, a router can 
apply some policy to filter the routing information. For example, a router 
receives/sends only routing information that matches certain criteria, or a routing 
protocol redistributes from other protocols only the routes matching certain 
criteria and modifies some attributes of these routes to satisfy its needs.
