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).

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.
