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.

router isis test-proc2

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-IS Link-State Packet (LSP) Errors
zLog Adjacency State Changes
zChange IS-IS LSP MTU Size
