5.7.5.1.4 Configuring OSPF
Open Shortest Path First is more suited for large area networks which experience frequent changes in
the links. It also allows for subnets. This 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. You can use the following menu to specify the area identifier, or other key
routing parameters as described in the following table.
Parameter

Area ID
