A Comparative Study on Routing Protocols: RIP, OSPF and EIGRP and Their Analysis Using GNS-3

On the Internet, the routing of a data packet is the most important process. A routing protocol specifies the way to a router so that it can be connected to the internetworks with the help of a protocol called an Internet protocol. Internet applications make use of many routing protocols like RIPvl, RIPv2, OSPF, EIGRP, IGRP, etc. Each routing protocols have their own methods of routing a packet. This paper presents a basic comparative study of RIP, OSPF, and EIGRP protocols. The RIP makes use of a distance vector algorithm to choose the best path for a packet, OSPF makes use of a link state algorithm to decide the best path for a packet and EIGRP makes use of diffusing update algorithms to decide a path for a packet. In this paper, we are comparing and analyzing the performance of routing protocols such as RIP, OSPF, and EIGRP to decide the best protocol for routing packets.
