Interior Gateway Routing Protocol (IGRP)
____________________________________
____________________________________
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
route, including bandwidth, delay, load,
MTU, and reliability
2.The maximum hop count of IGRP-routed
packets is 255 (default 100).
disadvantage
__________________
__________________
1. IGRP is considered a classful routing
protocol.

Classful routing protocols can not support variable length subnets.
Yes thats why we are using classless protocols for Variable Lenght Subnets (VLSM).
