An IPv6 NG MVPN is similar with the IPv4 NG MVPN whose framework is designed to transmit IP multicast traffic across a BGP/MPLS IP VPN. An NG MVPN uses BGP to transmit signaling information, and uses PIM-SM, PIM-SSM, P2MP TE, or mLDP to transmit data. The NG MVPN enables unicast and multicast services to be delivered using the same VPN architecture.
The main difference between IPv6 NG MVPN and the IPv4 NG MVPN is the IP version and multicast protocols used in the receiver side and source side. For an IPv6 NG MVPN network, IPv6 address is used in the multicast source private network and multicast receiver side private network.
