Multicast VLAN Registration

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).
