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).

Command Usage
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 568).
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 569).
3. Set the interfaces that will join the MVR as source ports or receiver ports
(see “Configuring MVR Interface Status” on page 572).
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 Assigning Static MVR Multicast Groups to
