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 e na ble 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, configur e ISO IGRP dynamic routing
on the router:
1. Enable the ISO IGRP routing proce ss and enter router configura-
tion mode.

2. Configure the NET or a ddress for the routing process.

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