Open Shortest Path First (OSPF) is a widely used and supported routing protocol. It's an interior gateway protocol (IGP) meaning it been designed to be used within a single autonomous system. It also falls under the category of Link-state routing protocols. Routers running OSPF learn about the enter network in order to create routes. They do this by flooding Link State Updates. There are three steps to the process. Become neighbours - Two routers running OSPF on the same link agree to form a neighbour relationship Exchange database information - The neighbouring routers swap their LSDB information with each other Choose the best routes - Each router chooses the best routes to add to its routing table based on the learned LSDB information #ccna #cisco #networking
