Configure ISO

IGRP Dynamic

Routing

The ISO IGRP is a dynamic distance-vector routing protocol designed by Cisco for routing an autonomous system that contains large, arbi- trarily complex networks with diverse bandwidth and delay character- istics.

To configure ISO IGRP, complete the tasks outlined in these sections. Only enabling ISO IGRP is required; the remaining task is optional, al- though you might be required to perform it, depending upon your spe- cific application:

zEnable ISO IGRP

zConfigure ISO IGRP Parameters

In addition, you can also configure these miscellaneous features:

zFilter routing information (refer to Create Packet-Forwarding Fil- ters and Establish Adjacencies)

zRedistribute routing information from one routing process to an- other (refer to Redistribute Routing Information)

zConfigure administrative distances (refer to Specify Preferred Routes)

Enable ISO IGRP

To configure ISO IGRP dynamic routing, you must enable the ISO IGRP routing process, identify the address for the router, and specify the interfaces that are to route ISO IGRP. Optionally, you can set a level for your routing updates when you configure the interfaces. CLNS routing is enabled by default on routers when you configure ISO IGRP. You can specify up to ten ISO IGRP routing processes.

In global configuration mode, configure ISO IGRP dynamic routing on the router:

1.Enable the ISO IGRP routing process and enter router configura- tion mode.

router iso-igrp [tag]

2.Configure the NET or address for the routing process. net network-entity-title

Although IS-IS allows you to configure multiple NETs, ISO IGRP al- lows only one NET per routing process.
