Multicast application in VPNs

A PE device that supports multicast for VPNs performs the following operations:
•
Maintains an independent set of multicast forwarding mechanisms for each VPN, including the
multicast protocols, PIM neighbor information, and multicast routing table. In a VPN, the device
forwards multicast data based on the forwarding table or routing table for that VPN.
•
Implements the isolation between different VPNs.
•
Implements information exchange and data conversion between the public network and VPN
instances.
For example, as shown in
group. Only receivers that belong to both the multicast group and VPN A can receive the multicast
data. The multicast data is multicast both in VPN A and on the public network.
Figure 10, a multicast source in VPN A sends multicast data to a multicast
