ASBR
Autonomous System Boundary Router

A router that exchanges routing information with routers belonging to other AS (Autonomous System). Such a router advertises AS external routing information throughout the Autonomous System. The paths to each AS boundary router are known by every router in the AS. AS boundary routers may be internal or area border routers, and may or may not participate in the backbone.
