Multicast Vlan Configuration Task List - HP A8800 Configuration Manual

Figure 21 Sub-VLAN-based multicast VLAN
After the configuration, IGMP snooping manages router ports in the multicast VLAN and member ports
in the sub-VLANs. When forwarding multicast data to Device A, Router A needs to send only one copy
of multicast traffic to Device A in the multicast VLAN, and Device A distributes the traffic to the multicast
VLAN's sub-VLANs that contain receivers.
