Document Summary

Igrp is a cisco-proprietary distance-vector protocol, designed to be more scalable than rip, its standardized counterpart. Other characteristics of igrp include: igrp supports only ip routing, igrp utilizes ip protocol 9, igrp routes have an administrative distance of 100, igrp, by default, supports a maximum of 100 hops. This value can be adjusted to a maximum of 255 hops: igrp is a classful routing protocol. Igrp uses bandwidth and delay of the line, by default, to calculate its distance metric. Reliability, load, and mtu are optional attributes that can be used to calculate the distance metric. Igrp requires that you include an autonomous system (as) number in its configuration. Only routers in the same autonomous system will send updates between each other. Routing protocol configuration occurs in global configuration mode. Router a, to configure igrp, we would type: The first command, router igrp 10, enables the igrp process. The 10 indicates the autonomous system number that we are using.
