An Eigrpv6 / Eigrpv4 Overview

Now, if you are new in Cisco IT network, in May you not quite sure EIGRPv6 protocol. I hope that this section of clarity quickly.

First, EIGRP Enhanced Interior Gateway Routing Protocol is the improved version of the Interior Gateway Routing Protocol (IGRP) and Cisco Systems. Currently, there are two versions of EIGRP, version 4 (EIGRPv4) and version 6 (EIGRPv6); EIGRPv4 works on IPv4 networks and EIGRPv6 runs on IPv6 networks.

EIGRPv6 works quite well in the same way as his predecessor EIGRPv4 and both versions of EIGRP performs the following:

• Allows EIGRP router (s) of a topology for each table with its neighbor in advertising, and then only the means of the topology table in the routing table of the router. The best way to a particular destination is considered as “disciple” of the second and the best path to a particular destination is considered as the possible successor.

• Both versions EIGRP, you use the transmitter or algorithm update (DUAL) for fast convergence and ensure trouble-free operation loop.

• Both versions EIGRP to send updates on the routing paths that have changed once EIGRP network convergence.

• Both versions EIGRP, EIGRP router interfaces to send hello packets every 5 seconds on a broadband connection and every 60 seconds on low bandwidth multi-links, for connecting the neighboring router.

• Both versions EIGRP on bandwidth, delay, reliability and support for roads, but the use of bandwidth and time. All measures EIGRP formula is:

* 256 ((K1 * Bw) + (K2 * Bw) / (256-Load) + (K3 * Delay) * (K5 / (reliability + K4)))

• In addition, both versions use EIGRP Reliable Transport Protocol (RTP), if necessary, for the delivery of EIGRP packets.
