Performance Analysis Of OSPF In Multicast Routing Using RPF Technique

Open Shortest Path first is most widely used interior gateway routing protocol, biggest it can update the routing in Autonomous system. Link-state routing protocols generate routing updates only when a change occurs in the network topology. When a link changes state, the device that detected the change creates a link-state advertisement (LSA) concerning that link and sends to all neighboring devices using a special multicast address. Each routing device takes a copy of the LSA, updates its link-state database (LSDB), and forwards the LSA to all neighboring devices. OSPF provides a technique RPF, the traffic may not occur and the packets can be freely to reach the destination router (DR).
