Note:
1. The router port should be in the multicast VLAN, otherwise the member ports cannot receive
multicast streams.
2. The Multicast VLAN won't take effect unless you first complete the configuration for the
corresponding VLAN owning the port on the 802.1Q VLAN page.
3. Configure the link type of the router port in the multicast VLAN as Tagged otherwise all the
member ports in the multicast VLAN cannot receive multicast streams.
4. After a multicast VLAN is created, all the IGMP packets will be processed only within the
multicast VLAN.

Application Example for Multicast VLAN:
Network Requirements

Multicast source sends multicast streams via the router, and the streams are transmitted to user A
and user B through the switch.
Router: Its WAN port is connected to the multicast source; its LAN port is connected to the switch.
The multicast packets are transmitted in VLAN3.
Specify the IP address with which the switch will replace the
source of IGMP packets.
Displays the dynamic router ports of the multicast VLAN.
Specify the static router port which is mainly used in the network
with stable topology.
Specify the forbidden router ports which is mainly used to forbid
ports becoming router ports.
Description
Snooping Required. Enable IGMP Snooping globally on the switch
