These different routing protocols are mainly categorized as static, dynamic and hybrid routing protocols. The selection of these routing protocols depends upon the network requirement and performance parameters of different real time applications. This paper investigates the performance of voice and video traffic in RIP, OSPF and EIGRP for flapping unstable links. We are considering the use of OPNET simulation tool to analyze the performance of these routing protocols . RIP, OSPF and EIGRP. In this investigation the impact of flapping links on convergence time, packet end-to-end delay, packets drop in IP network, voice jitter, video packet delay variation and HTTP page response time is considered. The simulated results showed that flapping links have a significant impact on the overall performance of IP based networks affecting specially the network convergence time and packet drops in the network. Keywords: Routing Protocols, Real Time Applications, Link flapping, Unstable networks. 1 INTRODUCTION Today's technology is based on IP routing [1], [14],[15]. There are commonly used routing protocols like Routing Information Protocol (RIP), Open Shortest Path First (OSPF) and Enhanced Interior Gateway Routing Protocol (EIGRP).
