Usage Information
You can congure 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.
