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).

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.
