Chapter 9: AI2524 OSI/CLNP Configuration Steps

Configure IS-IS Dynamic Routing

zDisable split horizon for ISO IGRP updates. no clns split-horizon

The default for all LAN interfaces is for split horizon to be enabled; the default for WAN interfaces on X.25, Frame Relay, or SMDS net- works is for split horizon to be disabled.

IS-IS is a dynamic routing specification described in ISO 10589. Cisco's implementation of IS-IS allows you to configure IS-IS as an ISO CLNS routing protocol.

To configure IS-IS, complete these tasks. Only enabling IS-IS is re quired; the remainder of the tasks are optional, although you might b required to perform them depending upon your specific application.

zEnable IS-IS

zAssign Multiple Area Addresses to IS-IS Areas

zConfigure IS-IS Parameters

zConfigure IS-IS Interface 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 IS-IS

To configure IS-IS dynamic routing, you must enable the IS-IS routing process, identify the address for the router, and specify the interfaces that are to route IS-IS. CLNS routing is enabled by default when you configure IS-IS dynamic routing. You can specify only one IS-IS pro- cess per router.

In global configuration mode, configure IS-IS dynamic routing on the router:

1.Enable IS-IS routing and enter router configuration mode. router isis [ tag]
