A comparative study of IGP and EGP routing protocols, performance evaluation along load balancing and redundancy across different AS

Routing is a vital part of a communication network that enables data transmission over a local and wide area networks. Each routing protocol has different features, performance, architecture, and algorithms to achieve the data communication and reliability. The data is moved around different network topologies and handled by different protocols within and outside different Autonomous Systems (AS). A reliable, secure and scalable communication platform relies on a correct combination of protocols. In this paper, we have performed a comparative analysis of Interior Gateway Routing Protocols (IGRP) and an Exterior Gateway Routing Protocol (EGP) performance evaluation. This is to find out the best protocol combination for any complex scenario to achieve fast and reliable communication. Hot Standby Routing Protocol (HSRP) and Gateway Load Balancing Protocol (GLBP) are also simulated to analyse the load balancing and redundancy parameter for Border Gateway Protocol (BGP).
