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
"Configuring MVR Domain Settings" on page 660 ).
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 "Configuring MVR Group Address Profiles" on
page 662 ).
3.
Set the interfaces that will join the MVR as source ports or receiver
ports (see
"Configuring MVR Interface Status" on page 665 ).
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
