Parameters
value: Specifies a DIS priority for the interface, ranging from 0 to 127.
level-1: Applies the DIS priority to Level-1.
level-2: Applies the DIS priority to Level-2.
Description
Use isis dis-priority to specify a DIS priority at a specified level for an interface.
Use undo isis dis-priority to restore the default priority of 64 for Level-1 and Level-2.
If neither level-1 nor level-2 is specified in this command, the DIS priority applies to both Level-1 and
Level-2.
On an IS-IS broadcast network, a router should be elected as the DIS at each routing level. You can
specify a DIS priority at a level for an interface. The greater the interface's priority is, the more
likelihood it becomes the DIS. If multiple routers in the broadcast network have the same highest DIS
priority, the router with the highest SNPA (Subnetwork Point of Attachment) address (SNPA
addresses are MAC addresses on a broadcast network) becomes the DIS.
IS-IS has no backup DIS and the router with a priority of 0 can also participate in DIS election.
NOTE:
This command is not available in loopback interface view.
Examples
# Configure the Level-2 DIS priority as 127 for VLAN-interface 10.
