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:
z
Enable ISO IGRP
z
Configure ISO IGRP Parameters
In addition, you can also configure these miscellaneous features:
z
Filter routing information (refer to Create Packet-Forwarding Fil-
ters and Establish Adjacencies)
z
Redistribute routing information from one routing process to an-
other (refer to Redistribute Routing Information)
z
Configure 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.

2. Configure the NET or address for the routing process.

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