Configuring IS-IS

To configure IS-IS routing, perform the following steps, beginning in global configuration mode:
Command
Step 1
Router(config)# router isis [ tag ]
Step 2
Router(config-router)# net
network-entity-title
Step 3
Router(config-router)# interface
interface-type interface-id
Step 4
Router(config-if)# ip address ip-address
mask
Step 5
Router(config-if)# ip router isis [ tag ]
Step 6
Router(config-if)# end
The following example shows how to configure IS-IS routing:
Router(config)# router isis
Router(config-router)# net 49.0001.0000.0000.000a.00
Router(config-router)# interface gigabitethernet 0
Router(config-if)# ip router isis
Router(config-if)# end
For more information about configuring IS-IS routing, refer to the "Configuring Integrated IS-IS"
chapter in the Cisco IOS IP and IP Routing Configuration Guide.

Verifying the IS-IS Configuration

To verify the IS-IS configuration, use the EXEC commands listed in

Table 10-7 IS-IS Show Commands

Command
Router# show ip protocols [summary]
Router# show isis database
Router# show clns neighbor
The ML Series does not support Connectionless Network Service Protocol (CLNS) routing.
Note
The following example shows the IS-IS configuration:
Router# show ip protocols
Routing Protocol is "isis"
Invalid after 0 seconds, hold down 0, flushed after 0
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Redistributing: isis
