distribution tree for a normal multicast VLAN. This makes it possible to
support common multicast services over a wide part of the network
without having to use any multicast routing protocol.

MVR maintains the user isolation and data security provided by VLAN
segregation by passing only multicast traffic into other VLANs to which
the subscribers belong. Even though common multicast streams are passed
onto different VLAN groups from the MVR VLAN, users in different
IEEE 802.1Q or private VLANs cannot exchange any information (except
through upper-level routing services).

General Configuration Guidelines for MVR

1. Enable MVR globally on the switch, select the MVR VLAN, and add

the multicast groups that will stream traffic to attached hosts (see
“Configuring Global MVR Settings” on page 15-14).

2. Set the interfaces that will join the MVR as source ports or receiver

ports (see “Web – Click MVR, Port Information or Trunk
Information.” on page 15-16).

3. Enable IGMP Snooping to a allow a subscriber to dynamically join or

leave an MVR group (see “Configuring IGMP Snooping and Query
Parameters” on page 4).
Note that only IGMP version 2 or 3 hosts can
issue multicast join or leave messages.
