About IPv6 PIM

IPv6 Protocol Independent Multicast (IPv6 PIM) provides IPv6 multicast forwarding by leveraging IPv6 unicast static routes or IPv6 unicast routing tables generated by any IPv6 unicast routing protocol. IPv6 PIM uses the underlying IPv6 unicast routing to generate an IPv6 multicast routing table without relying on any particular IPv6 unicast routing protocol.

IPv6 PIM uses the RPF mechanism to implement IPv6 multicast forwarding. For more information about RPF, see "Configuring IPv6 multicast routing and forwarding."
