Usage
Information
You can configure priorities independently for Level 1 and Level 2. Priorities determine which
router on a LAN is the designated router. Priorities are advertised within hellos. The router with
the highest priority becomes the designated intermediate system (DIS).
NOTE: Routers with a priority of 0 cannot be a designated router.
Setting the priority to 0 lowers the chance of this system becoming the DIS, but does not
prevent it. If all the routers have priority 0, one with highest MAC address becomes DIS even
though its priority is 0.
