Usage Guidelines

An area border router (ABR) can belong to two or more areas. One of the areas must be a backbone area. An ABR is used to connect the backbone area and non-backbone areas. The connection with the backbone area can be physically or logically.

An AS boundary router (ASBR) exchanges routing information with other ASs. An ASBR may not reside at the boundary of an AS. It can be an internal device or an ABR. If an OSPF device imports external routes, the device is an ASBR.

This command can view information about the ABRs and ASBRs of OSPF.
