Parameters
value: Specifies a DIS priority in the range of 0 to 127.

level-2: Applies the DIS priority to Level-2.
Usage guidelines
If neither level-1 nor level-2 is specified, the DIS priority applies to both Level-1 and Level-2.
On an IS-IS broadcast network, a router must be elected as the DIS at each routing level. 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 Subnetwork Point of Attachment (SNPA) address (SNPA addresses are MAC addresses on a
broadcast network) becomes the DIS.
IS-IS has no backup DIS. The router with a priority of 0 can also participate in DIS election.
