Chapter 11 Configuring Networking Protocols
Verifying the IS-IS Configuration
Example 11-16 shows an example of IS-IS routing configuration.
Example 11-16 Configuring 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 11-7. Example 11-17 shows
examples of the commands in Table 11-7 and their output.
Note
The ML Series does not support Connectionless Network Service Protocol (CLNS) routing.
Example 11-17 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
Command Purpose
Step 1
Router(config)# router isis [
tag
]
Defines IS-IS as the IP routing protocol.
Step 2
Router(config-router)# net
network-entity-title
Configures network entity titles (NETs) for the
routing process; you can specify a name for a
NET as well as an address.
Step 3
Router(config-router)# interface
interface-type interface-id
Enters interface configuration mode.
Step 4
Router(config-if)# ip address
ip-address
mask
Assigns an IP address to the interface.
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.
Table 11-7 IS-IS Show Commands
Command Purpose
Router# show ip protocols [summary]
Displays the protocol configuration.
Router# show isis database
Displays the IS-IS link-state database.
Router# show clns neighbor
Displays the ES and IS neighbors.
