Figure 10-3 Port-based IPv6 multicast VLAN
After the configuration, upon receiving an MLD message on a user port, Switch A tags the
message with the IPv6 multicast VLAN ID and relays it to the MLD querier, so that MLD
Snooping can uniformly manage the router ports and member ports in the IPv6 multicast VLAN.
When forwarding multicast data to Switch A, Router A needs to send only one copy of multicast
traffic to Switch A in the IPv6 multicast VLAN, and Switch A distributes the traffic to all the
member ports in the IPv6 multicast VLAN.
