Changing the DR priority
Syntax:
ip pim-sparse dr-priority [0-4294967295]
This command changes the router priority for the DR election process in the current VLAN. A numerically higher value means a higher priority. If the highest priority is shared by multiple routers in the same VLAN, the router with the highest IP address is selected as the DR.
A 0 (zero) value disables DR operation for the router on the current VLAN.
