Specifies the DR (designated router) priority of an IPv6 PIM-enabled interface.
The default priority value is 1.
Interface configuration mode
Important
Use the ipv6 router pim command to globally enable IPv6 PIM routing before setting the DR priority.
The DR receives all Join messages from the hosts below it. The DR then sends only one Join message to the rendezvous point (RP) on behalf of the hosts. Similarly, the DR attached to the source registers with the RP.
The router with the highest DR priority is the elected DR for an interface. If multiple routers have the same DR priority, the router with the highest IP address is the elected DR.
The no ipv6 pim dr-priority form of the command restores the default priority of 1.
The following example specifies the DR priority on a virtual Ethernet (VE) interface.
device# configure terminal device(config)# interface ve 30 device(config-if-ve-30)# ipv6 pim dr-priority 100
