AI2524 Router Card User’s Manual

Warning: If you have not configured the router to route CLNS pack- ets dynamically using ISO IGRP or IS-IS, you must as sign an address to the router.

You also must enable ISO CLNS for each interface you want to pass ISO CLNS packet traffic to end systems, but for which you do not want to perform any dynamic routing on the interface. This is done au- tomatically when you configure IS-IS or ISO IGRP routing on an in- terface; however, if you do not intend to perform any dynamic routing on an interface, you must manually enable CLNS. You can assign an NSAP address for a specific interface. This allows the Cisco IOS soft- ware to advertise different addresses on each interface. This is useful if you are doing static routing and need to control the source NET used by the router on each interface.

In interface configuration mode, configure CLNS on an interface:

1.Enable ISO CLNS for each interface. clns enable

2.Optionally, assign an NSAP address to a specific interface. clns net {nsap-addressname}

Examples: Basic Static Routing

Configuring FDDI, Ethernets, Token Rings, and serial lines for CLNS can be as simple as enabling CLNS on the interfaces. This is all that is ever required on serial lines using HDLC encapsulation. If all systems on an Ethernet or Token Ring support ISO 9542 ES-IS, then nothing else is required.

Example 1

This example illustrates how an Ethernet and a serial line can be con- figured:

1. Enable clns packets to be routed:

clns routing

2. Configure this network entity title for the routing process:

clns net 47.0004.004d.0055.0000.0C00.BF3B.00
