An ABR deletes type 4, 5 LSAs from internal routers, sends them a default route of 0.0.0.0 and turns itself into a default gateway.
Recently the industry has been focusing on ways to use adaptive bit rate (ABR) and marry it with multicast delivery of linear channels.
An ASBR creates External LSAs for external addresses and floods them to all areas via ABR.
;Area border router (ABR): An area border router is a router that connects one or more areas to the main backbone network.
If there are multiple ABRs, as might be required for high availability, routers interior to the TSA will send non-intra-area traffic to the ABR with the lowest intra-area metric (the "closest" ABR) but that requires special configuration.
It visualizes the following activities: the ASBR imports external addresses with a type 7 LSA, the ABR converts a type 7 LSA to type 5 and floods it to other areas, the ABR acts as an "ASBR" for other areas.
