Priorities determine whichrouter on a LAN is the designated router. Priorities are advertised within hellos. The router withthe 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 notprevent it. If all the routers have priority 0, one with highest MAC address becomes DIS eventhough its priority is 0.881
