Port-based IPv6 multicast VLAN

As shown in Figure 93:

Figure 93: Port-based IPv6 multicast VLAN

MLD snooping manages the router ports and member ports in the IPv6 multicast VLAN. When Switch A receives IPv6 multicast data from the IPv6 multicast source, it sends only one copy of the IPv6 multicast data to the IPv6 multicast VLAN on Switch B. Then, Switch B sends a separate copy to each user port in the IPv6 multicast VLAN.
