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]

Figure 9-5, and the example configuration illustrate how to configure

a single area:
