Optimal selection of Dynamic Routing Protocol with real time case studies

Selection of a Dynamic Routing Protocol has great impact on the utilization of various network resources. The factors like usage of bandwidth and behaviour towards growing entries in the routing table, determine the suitability of a protocol. In this paper, we have measured and compared the bandwidths utilised by the three IPv4 dynamic routing protocols, RIPv2 (Routing Information Protocol), EIGRP (Enhanced Interior Gateway Routing Protocol) and OSPFv2 (Open Shortest Path First) with real time case studies. We have also addressed the issue of choosing the optimal protocol as per the network specifications.
