Application Scenarios for Multicast VPN

Multicast VPN isolates multicast services of different VPN instances in an autonomous system (AS).

Figure 1 shows a BGP/MPLS IP VPN network with a single AS. On the network, PE1, PE2, and PE3 are configured with two VPN instances: VPNA and VPNB. Each VPN instance has the same Share-Group address and joins the same MD on the PE devices. After a Share-MDT is established, protocol and data packets from the VPNs can be transmitted through corresponding multicast tunnels (MTs).

To implement VPN multicast services in an AS, perform the following configurations:
