Communication technology facilitates provision of such services as file transferring, print sharing, video streaming. Internet is a global system of interconnected networks. Computer communication networks are based on a technology that provides the technical infrastructure, where routing protocols are used to transmit packets across the internet. Routing protocols specify how routers communicate with each other by disseminating information. Routing protocols are broadly categorized into Interior and Exterior Gateway routing protocols. While Interior Gateway protocols disseminate packets within an Autonomous System (AS), Exterior Gateway protocols send packets from an AS to another. This work review the performance of Interior Gateway Protocols; EIGRP, OSPF, RIP and IS-IS. Considering so many performance metrics like convergence, scale of networks, HTTP page response and packets loss, comparative analysis of the protocols is done.
