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.
This value sets the router priority. The higher the value, the higher the priority. The range
is from 0 to 127. The default is 64.
(OPTIONAL) Specify the priority for Level 1. This setting is the default.
(OPTIONAL) Specify the priority for Level 2.
