The isis dis-name command configures a name for the Designated Intermediate System (DIS).
The undo isis dis-name command deletes the name configured for the DIS.
By default, no name is configured for DIS.

Usage Scenario
For easy identification and memorization, you can run the isis dis-name command to configure a DIS name.
Prerequisites
An IS-IS process has been created, and the IS-IS process has been enabled on a specified broadcast interface.
Configuration Impact
If the local device is the DIS, the DIS name can be associated with a system ID, and the DIS name can be advertised through pseudonode LSPs.
Precautions
The isis dis-name command takes effect only on the DIS.
If you run the isis circuit-type command to simulate a broadcast interface as a P2P interface, the isis dis-name command cannot be executed on this interface. If you run the undo isis circuit-type command to restore the interface to a broadcast interface, the isis dis-name command can be executed on this interface.
