provider, and to configure each interface that participates in the MVR protocol as a source
port or receiver port.
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).
