What. is OSPF ?. OSPF stands for Open . Shortest. . Path. First. OSPF . considered. as . thired. layer Protocol . OSPF is . Industry Standard that means it is not monopoly . . . for any company . Distance Vector and Link State. RIP. OSPF. Internet Routing. IP implements datagram forwarding. Both hosts and routers. Have an IP module. Forward datagrams. IP forwarding is table-driven.
