Figure 3-2 Port-based multicast VLAN

After the configuration, upon receiving an IGMP message on a user port, Switch A tags the message

with the multicast VLAN ID and relays it to the IGMP querier, so that IGMP Snooping can uniformly

manage the router ports and member ports in the 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 multicast VLAN,

and Switch A distributes the traffic to all the member ports in the multicast VLAN.

For information about IGMP Snooping, router ports, and member ports, refer to

Configuration.

For information about VLAN tags, refer to VLAN Configuration.
