Chapter 9: AI2524 OSI/CLNP Configuration Steps

IS-IS

To run IS-IS instead of ISO IGRP, use this configuration. The illustra- tion in Figure 9- still applies. Ethernet interface 2 is configured for IS-IS routing and is assigned the tag of test-proc2.

net 49.0002.0002.bbbb.bbbb.bbbb.00 router isis test-proc2

interface serial 2

clns router iso-igrp test-proc1

interface ethernet 2

clns router IS-IS test-proc2

To allow CLNS packets only to blindly pass through an interface with- out routing updates, you could use a simple configuration. This exam- ple shows such a configuration:

clns routing interface serial 2

This permits serial 2 to pass CLNS packets without having CLNS rout- ing turned on:

clns enable

Configure IS-IS Parameters

Cisco's IS-IS implementation allows you to customize certain IS-IS parameters. You can perform the optional tasks:

zSpecify Router-Level S upport

zConfigure IS-IS Authentication Passwords

zIgnore IS-ISLink-State Packet (LSP) Errors

zLog Adjacency State Changes

zChange IS-IS LSP MTU Size
