____________________________________

IGRP is an interior gateway protocol

invented by Cisco to replace the RIP.

It is a distance-vector routing protocol

used by routers to exchange routing data

within an autonomous system.



Important points
_______________
1. IGRP supports multiple metrics for each

the route, including bandwidth, delay, load,

MTU, and reliability

2.The maximum hop count of IGRP-routed

packets are 255 (default 100).



disadvantage
__________________
1. IGRP is considered a classful routing

protocol.
