EGISTRATION
Multicast VLAN Registration (MVR) is a protocol that controls access to a
single network-wide VLAN most commonly used for transmitting multicast
traffic (such as television channels or video-on-demand) across a service
provider’s network. Any multicast traffic entering an MVR VLAN is sent to
all attached subscribers. This protocol can significantly reduce to
processing overhead required to dynamically monitor and establish the
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).

Use the MVR Configuration page to enable MVR globally on the switch,
select the VLAN that will serve as the sole channel for common multicast
streams supported by the service provider, and to configure each interface
that participates in the MVR protocol as a source port or receiver port.
