9.1 Introduction to Multicast VLAN

Generally, when users in different virtual LANs (VLANs) order a multicast stream, each
of these VLANs copies the same multicast stream to itself. In this method, a great deal
of bandwidth is wasted.
Multicast VLAN is used to solve this problem. You can configure a multicast VLAN, join
related switch ports into this VLAN and enable the IGMP Snooping function to make
users in different VLANs share the same multicast VLAN. After doing that, multicast
streams are transmitted only through the multicast VLAN, and therefore the bandwidth
is saved. Additionally, the absolute isolation between the multicast VLAN and the user
VLANs guarantees the security of the network.

9.2 Multicast VLAN Configuration

9.2.1 Configuration Tasks

Though multicast VLAN is mainly implemented at layer 2 switching, you must configure
it on both layer 2 and 3 switches.
The following table describes the multicast VLAN configuration tasks
