1.2.5 Configuring Multicast VLAN

In old multicast mode, when users in different VLANs order the same multicast group,
the multicast stream is copied to each of the VLANs. This mode wastes a lot of
bandwidth.
By configuring a multicast VLAN, adding switch ports to the multicast VLAN and
enabling IGMP Snooping, you can make users in different VLANs share the same
multicast VLAN. This saves bandwidth since multicast streams are transmitted only
within the multicast VLAN, and also guarantees security because the multicast VLAN is
isolated from user VLANs.
Multicast VLAN is mainly used in Layer 2 switching, but you must make corresponding
configuration on the Layer 3 switch.
