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
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.
