ABR: Area Border Router
Area Border Router (ABR) is a router located on the border of one or more OSPF areas that connect those areas to the backbone network. ABRs are considered members of both the OSPF backbone and the attached areas. They therefore maintain routing tables describing both the backbone topology and the topology of the other areas.
