Area Configuration and Link Failure Effect in IP Networks Using OSPF Protocol
Open Shortest Path First (OSPF) protocol is widely deployed in IP networks to manage intra-domain routing. An OSPF is a link-state protocol, in which routers establish relationships developing neighbors, enabling each to build a consistent, global view of the routing topology. This paper is based on overview of OSPF comprising different types of routes, routers, networks, areas and protocols/processes used in OSPF. The authors used OPNET IT guru academic edition 9.1 network simulators for six different network scenarios to calculate the shortest path from source to destination router.
