Introducing Open Shortest Path First (OSPF)


Link-state routing protocols build their routing tables independently based
on route updates they receive from their neighbors. Link-state protocols
do not merge the routing tables of neighbor routers. Link-state protocols
enable routers to have a clear image of neighbors, network topology, and
routes to their neighbors and beyond by maintaining not just routing tables
but also topology and neighbor tables.
 OSPF complies with all these link-state routing protocol characteristics
