Characteristics of IGRP ( Interior Gateway Routing protocol):

1.   IGRP is a distance-vector routing protocol developed by Cisco.

2.   IGRP uses a composite metric which includes Bandwidth, Delay (by default), reliability, Load and MTU.

3.   It broadcasts updates every 90 seconds with a hold-down period of 280 seconds.

4.   To speed up convergence triggered updates are used when network changes occur.

5.   IGRP requires an AS number in its router command.

6.   For routers to share routing information they must be in the same AS number.

7.   IGRP maximum hop count is 255. It defaults to 100 and it is usually set to 50 or less.

8.   IGRP AD is 100.
