Example: Configuring VSI-based IGMP snooping
Network configuration
As shown in Figure 18:
There are three sites in VPN a. They are connected through the VPLS network.
In VLAN 100, Source in Site 1, Host A in Site 2, and Host B in Site 3 communicate with CE 1, CE 2, and CE 3, respectively.
Configure the devices so that Host A and Host B can receive multicast data from Source.

Procedure
Assign an IP address and subnet mask to each interface on the VPLS network, as shown in Table 6. (Details not shown.)
Configure OSPF on the switches on the VPLS network. (Details not shown.)
