IPv6 MVPN support

IPv6 multicast support in SR OS allows operators to offer customers IPv6 multicast MVPN service. An operator uses IPv4 mLDP or RSVP-TE core to carry IPv6 c-multicast traffic inside IPv4 mLDP or RSVP-TE provider tunnels (p-tunnels). The IPv6 customer multicast on a specific MVPN can be blocked, enabled on its own or in addition to IPv4 multicast per PE or per interface. When both IPv4 and IPv6 multicast is enabled for a specific MVPN, a single tree is used to carry both IPv6 and IPv4 traffic. Figure: IPv6 MVPN example shows an example of an operator with IPv4 MPLS backbone providing IPv6 MVPN service to Customer 1 and Customer 2.
