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.
