Performance analysis of selected interior gateway dynamic routing protocols such as RIPv2, EIGRP and OSPF and their different performance issues have been investigated in this article. We have also presented a simulated work and the performance of redistribution command to establish communication between end users of different networks with different routing protocol. Route redistribution technology between diverse routing protocols has significant importance. Route redistribution is certainly easily realized and cost effective technique. Through using it we can also settle Tactical Internet Communication. Besides, comparative analysis among several routing protocol shows that the EIGRP protocol is better than the OSPF and RIPv2 routing protocol. But sometime EIGRP is held back by its proprietary features and costs. OSPF is better than other in large networks where its hierarchical nature increases scalability. And RIPv2 is useful in local and small area network. The redistribution command shows the way to communicate with different routing protocols.
