Configure Open Shortest Path First (OSPF) parameters
Open Shortest Path First (OSPF) is an Interior Gateway Protocol (IGP) developed for IP networks
based on the shortest path first or link-state algorithm.
The router uses link-state algorithms to send routing information to all nodes in a network by
calculating the shortest path to each node based on a topography of the network constructed by each
node. Each router sends that portion of the routing table that describes the state of its own links and
the complete routing structure (network topography).
The advantage of the shortest path first algorithms is that they result in smaller, more frequent
update everywhere. They converge quickly, thus preventing such problems as routing loops and
Count-to-Infinity (where routers continuously increment the hop count to a particular network). This
makes for a stable network.
To use OSPF on the router, a valid configuration file must exist in the router’s filing system.
