Configuring the Open Shortest Path First Protocol

Open Shortest Path First (OSPF) is more suited for large area networks which experience frequent changes in the links. It also handles subnets much better than RIP. OSPF protocol actively tests the status of each link to its neighbors to generate a shortest path tree, and builds a routing table based on this information. OSPF then utilizes IP multicast to propagate routing information. A separate routing area scheme is also used to further reduce the amount of routing traffic.

Note: The OSPF protocol implemented in this device is based on Version 2 (RFC 2328). It also supports Version 1 (RFC 1583) compatibility mode to ensure that the same method is used to calculate summary route costs throughout the network when older
