Configuring ISO CLNS Routing
Beginning in privileged EXEC mode, follow these steps to enable IS-IS and specify the area for each
instance of the IS-IS routing process:
Command
Step 1
configure terminal
Step 2
clns routing
Step 3
router isis [area tag]
Step 4
net network-entity-title
Step 5
is-type {level-1 | level-1-2 |
level-2-only}
Step 6
exit
Step 7
interface interface-id
Step 8
ip router isis [area tag]
Step 9
clns router isis [area tag]
Step 10
ip address ip-address-mask
Step 11
end
Step 12
show isis [area tag] database detail
Step 13
copy running-config startup-config
To disable IS-IS routing, use the no router isis area-tag router configuration command.
This example shows how to configure three routers to run conventional IS-IS as an IP routing protocol.
In conventional IS-IS, all routers act as Level 1 and Level 2 routers (by default).
Router A
Switch(config)# clns routing
Switch(config)# router isis
Switch(config-router)# net 49.0001.0000.0000.000a.00
Switch(config-router)# exit

Purpose
Enter global configuration mode.
Enable ISO connectionless routing on the switch.
Enable the IS-IS routing for the specified routing process and enter IS-IS
routing configuration mode.
(Optional) Use the area tag argument to identify the area to which the IS-IS
router is assigned. You must enter a value if you are configuring multiple
IS-IS areas.
The first IS-IS instance configured is Level 1-2 by default. Later instances
are automatically Level 1. You can change the level of routing by using the
is-type global configuration command.
Configure the NETs for the routing process. If you are configuring
multiarea IS-IS, specify a NET for each routing process. You can specify a
name for a NET and for an address.
(Optional) You can configure the router to act as a Level 1 (station) router,
a Level 2 (area) router for multi-area routing, or both (the default):
•
level-1—act as a station router only
•
level-1-2—act as both a station router and an area router
•
level 2—act as an area router only
Return to global configuration mode.
Specify an interface to route IS-IS, and enter interface configuration mode.
If the interface is not already configured as a Layer 3 interface, enter the no
switchport command to put it into Layer 3 mode.
Configure an IS-IS routing process for ISO CLNS on the interface and
attach an area designator to the routing process.
Enable ISO CLNS on the interface.
Define the IP address for the interface. An IP address is required on all
interfaces in an area enabled for IS-IS if any one interface is configured for
IS-IS routing.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
