Open Shortest Path First (OSPF). It is an open standard routing protocol that’s been implemented by a wide variety of network vendors. By using the Dijkstra algorithm. A shortest path tree is constructed, and then the routing table is populated with the resulting best paths.
OSPF provides the following features:
These two elements are the basic elements of OSPF configuration:
