Link Failure Analysis On EIGRP And OSPF Protocol With Ipv4 And Ipv6 On Mixed Topology Networks

Abstract
In this paper, the disconnecting time duration after a main connection link fails in Enhanced Interior Gateway Routing Protocol (EIGRP) and Open Shortest Path First Protocol (OSPF) on the mixed topology networks is analyzed. The time duration, from a link failure to a new link established, is defined as time out and is measured while transmitting IPv4, IPv6, Tunnel_4over6, and Tunnel_6over4 packets.In addition, two mixed topology networks are using EIGRP or OSPF protocol and connected with Border Gateway Protocol(BGP). For Simulation, GNS3 is used to simulate the transmission on both networks and WIRESHARK is used for functions analysis. Finally, the average time out results from EIGRP are longer than ones from OSPF in both IPv4 and IPv6 networks andmost time outs are twice longer on IPv6 network than IPv4 network.
