Views

Default command level
2: System level
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.
Usage guidelines
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 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.
Examples
# Configure the DIS priority on Level-2 as 127 for GigabitEthernet 1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/1
[Sysname-GigabitEthernet1/1] isis dis-priority 127 level-2
