Explanation
OSPF is a link-state routing protocol that requires all routers in the same domain to maintain a map of the network. This map is called the link-state database (LSDB) and it contains information about the topology and the state of each link. Each router independently calculates the shortest path to every destination in the network using the Dijkstra algorithm. OSPF routers exchange routing information by flooding link-state advertisements (LSAs) to their neighbors. LSAs are acknowledged by the receivers to ensure reliable delivery.
