Open Shortest Path First (OSPF) is an adaptive, interior gateway routing protocol for Internet Protocol (IP) networks. It routes IP packets within a single independent system, detecting changes such as link failures. OSPF determines the shortest path around these failures for each route.
Avery important thing to important thing to monitor when managing an OSPF network is how each router in the OSPF network sees other routers in the network. You want to be on the lookout for OSPF neighbor states. Changes may indicate a network problem.
For more information on monitoring OSPF networks and OSPF neighbor states, see the blog Monitoring OSPF Neighbor State Changes. You may have some capabilities you didn’t know you had! And don’t forget to check out the Cisco tech link note in the blog too, for detailed information.
