Open Shortest Path First (OSPF) is a type of routing protocol used in computer networks, particularly in IP networks. It is an interior gateway protocol that helps routers determine the most efficient path for data to take between nodes on a network. OSPF is an open standard protocol, which means it can be used across different vendors and platforms, making it popular in enterprise and service provider networks. It is known for its fast convergence time, scalability, and ability to support multiple paths for redundancy. OSPF operates on the basis of link state technology which means it exchanges the local routing information with the neighboring routers it is connected to.
