Configuring IS-IS
To configure IS-IS routing, perform the following steps, beginning in global configuration mode:
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.
Note The ML Series does not support Connectionless Network Service Protocol (CLNS) routing.
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

Step 4
Router(config-if)# ip address ip-address
mask

Step 5
Router(config-if)# ip router isis [ tag ]
Specifies that this interface should run IS-IS.
Step 6
Router(config-if)# end
Returns to privileged EXEC mode.
