ABR routers refer to routers that operate in an OSPF (Open Shortest Path First) network and connect to multiple areas within the network. It is a specialized skill involving the configuration, management, and troubleshooting of such routers. An ABR (Area Border Router) is responsible for exchanging routing information between different areas in an OSPF network, optimizing the flow of traffic, and ensuring redundancy in case of network failures. Mastery of ABR routers requires a deep understanding of OSPF protocols and network architecture.
