In Figure: Multicast VPN traffic flow, VPRN-1 is the source VPRN instance and VPRN-2 and VPRN-3 are receiver VPRN instances. The PIM/IGMP JOIN received on VPRN-2 or VPRN-3 is for (S1, G1) multicast flow. Source S1 belongs to VPRN-1. Because of the route export policy in VPRN-1 and the import policy in VPRN-2 and VPRN-3, the receiver host in VPRN-2 or VPRN-3 can subscribe to the stream (S1, G1).
