Usage
You can configure priorities independently for Level 1 and Level 2. Priorities determine which
Information
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 0 to 127. The default is 64.
(OPTIONAL) Specify the priority for Level 1. This is the default.
(OPTIONAL) Specify the priority for Level 2.
Introduced on the S4810.
NOTE: Routers with a priority of 0 cannot be a designated router.
