  • Implementing ospfImplementing ospf

    The routing algorithm of OSPF maintains a complex database of topology information, which routers use to maintain full knowledge of distant routers. OSPF is a classless, link-state routing protocol that is widely deployed in many networks. OSPF load-balances across four equal metric paths by default on Cisco routers. OSPF supports plaintext an...
