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 can not 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:

¾Network 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.

Switch: Port 3 is connected to the router and the packets are transmitted in VLAN3; port 4 is connected to user A and the packets are transmitted in VLAN4; port 5 is connected to user B and the packets are transmitted in VLAN5.

User A: Connected to Port 4 of the switch.

User B: Connected to port 5 of the switch.

Configure a multicast VLAN, and user A and B receive multicast streams through the multicast VLAN.
