This solution allows delivery of IPv6 multicast traffic in an IP-VRF using an IPv4 multicast in the underlay network. The protocol used to build multicast trees in the underlay network is PIM Sparse Mode.

This solution optimizes the delivery of multicast to a VLAN over an Ethernet VPN (EVPN) network. Without this solution IPv6 multicast traffic in a VLAN is flooded to all Provider Edge(PE) devices which contain the VLAN.
