Setting a Priority to Determine the Designated Router for IPv6

You can influence whether a particular router is selected as the designated router with the ipv6 pim dr-priority command. A higher priority value increases the likelihood that a router is selected as the designated router, while a lower value decreases the likelihood. The ipv6 pim dr-priority command in Router Configuration mode sets the designated router priority on all the PIM interfaces on the router. To override this global setting on a particular interface, use the ipv6 pim dr-priority command in Interface Configuration mode.

Note: You cannot configure the designated router priority on PIM DM interfaces.
