Adding Multicast Addresses to VLANs
Multicast filtering can be dynamically configured using IGMP Snooping
and IGMP Query messages as described in “Configuring IGMP

switch. First add all the ports attached to participating hosts to a common
VLAN, and then assign the multicast service to that VLAN group.
