Analysis the Advantages and Packet Format of EIGRP

EIGRP is an enhanced version of IGRP, and is a private routing protocol of Cisco Systems, Inc. We analyze the packet format of EIGRP and the advantages including PDM, RTP, DUAL, rapid convergence times, low usage of network resources, and route summarization. In Packet Tracer simulation software, the simulation experiments configure EIGRP in a simple network topology. The simulation results show the different structure of EIGRP packet, and EIGRP supports well route summarization and provides extremely quick convergence times with minimal network traffic for low usage of network resources.
