Multicast VLAN Registration for IPv4
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).

General Configuration Guidelines for MVR:
1. Enable MVR for a domain on the switch, and select the MVR VLAN (see
2. Create an MVR profile by specifying the multicast groups that will stream traffic to
attached hosts, and assign the profile to an MVR domain (see
3. Set the interfaces that will join the MVR as source ports or receiver ports (see
4. For multicast streams that will run for a long term and be associated with a stable set of
hosts, you can statically bind the multicast group to the participating interfaces (see
