AIS AI2524 Example Dynamic Routing within the Same Area, Clns router iso-igrp tag level

Chapter 9: AI2524 OSI/CLNP Configuration Steps

You can assign a meaningful name for the routing process by using the tag option. You can also specify a name for a NET in addition to an address. For information on how to assign a name, see Specify Short- cut NSAP Addresses.

You can configure an interface to advertise L evel2 information only. This option reduces the amount of router-to-router traffic by telling th Cisco IOS software to send out only L evel2 routing updates on certain interfaces. Level 1 information is not passed on the interfaces for which the Level 2 option is set.

In interface configuration mode, enable ISO IGRP on specified inter faces and set the level type for routing updates:

clns router iso-igrp tag [level 2]

Example: Dynamic Routing within the Same Area

Figure 9-5, and the example configuration illustrate how to configure dynamic routing within a routing domain. The router can exist in on or more areas within the domain. The router named Router A exists in a single area:
