OSPF, or Open Shortest Path First, is a routing protocol used to exchange routing information within a single autonomous system (AS) in a network. OSPF is typically used in large enterprise networks because it offers more flexibility and better performance compared to other routing protocols. OSPF helps to determine the fastest and most efficient paths for data packets to travel through the network, and it adapts to changes in the network topology, such as added or removed routers, to maintain efficient routing. OSPF also supports hierarchical design features, allowing for greater scalability and easier network management.
