Multicast VLAN Registration

M VLAN R
ULTICAST EGISTRATION
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:
◆
Enable MVR globally on the switch, and select the MVR VLAN (see

Specify the multicast groups that will stream traffic to attached

hosts (see "Configuring MVR Group Address Ranges" on page
Set the interfaces that will join the MVR as source ports or receiver

with a stable set of hosts, you can statically bind the multicast
group to the participating interfaces (see
