5.3.4 Configuring DIS Priority

In a broadcast network, IS-IS needs to select a router as DIS.
When a DIS needs to be selected from the IS-IS neighbors on the broadcast network,
the Level-1 DIS and Level-2 DIS should be selected respectively. The higher priority a
DIS has, the more likely it is to be chosen. If two or more routers with the highest
priorities exist on the broadcast network, the router that has the greatest MAC
address will be chosen. For adjacent routers that have the same priority of 0, the
router that has the greatest MAC address will still be chosen.
Level-1 DIS and Level-2 DIS are elected respectively. You can set different priorities
for DISs at different levels to be elected.
Follow these steps to configure DIS priority:
