The implementation of IS-IS supports RFC 2763, which describes a mechanism for mapping IS-IS system IDs to the hostnames of the devices with those IDs. The following task disables IS-IS name mapping.
Procedure
-
Enter the
configure terminal command to access global configuration mode.
device# configure terminal
-
Enter the
router isis command to enter IS-IS router configuration mode and enable IS-IS on the device.
device(config)# router isis
-
Enter the
hostname disable command to disable IS-IS name mapping.
device(config-isis-router)# hostname disable
Example
The following example globally disables IS-IS name mapping.
device# configure terminal
device(config)# router isis
device(config-isis-router)# hostname disable
