Enabling 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.
Beginning in privileged EXEC mode, follow these steps to enable ISO IGRP:
Command
Step 1
configure terminal
Step 2
clns routing
Step 3 router iso- igrp [tag]
Step 4 net network-entity-title
Step 5
exit
Step 6
interface interface-id
Step 7
clns router iso-igrp [[tag] [level 2]]
Step 8
exit
Step 9 end

shows the default ISO IGRP configuration.
Purpose
Enter global configuration mode.
Enable ISO connectionless routing on the switch.
Enable the ISO IGRP routing process and enter router configuration mode.
(Optional) Assign a meaningful name (tag) for the routing process.
Configure the NET or address for the routing process. You can configure
only one NET per routing process.
Enter the NET or process in the format XX.XXXX. ... .XXX.XX
Return to global configuration mode.
Specify an interface to route ISO IGRP and enter interface configuration
mode. If the interface is not already configured as a Layer 3 interface, enter
the no switchport command to put it into Layer 3 mode.
Enable ISO IGRP on the specified interface.
(Optional) tag—routing process name.
•
(Optional) Set the routing type (level 2) for routing updates. When
•
selected, this option reduces the amount of router-to-router traffic
because the interface sends out only Level 2 routing updates and does
not pass on Level 1 information.
Return to global configuration mode.
Repeat steps 5 and 6 to enable ISO IGRP on other interfaces.
Return to privileged EXEC mode.
