4.8.7 MVR Configuration
In multicast VLAN networks, subscribers to a multicast group can exist in more than one VLAN. If the VLAN boundary restrictions
in a network consist of Layer 2 switches
Multicast VLAN Registration (MVR)
is a protocol for Layer 2 (IP)-networks that enables multicast-traffic from a source VLAN to
be shared with subscriber-VLANs. The alternative would be to use PIM or a similar protocol to route the traffic through a Layer 3-
network, it might be necessary to replicate the multicast stream to the same group in different subnets, even if they are on the
same physical network. Multicast VLAN Registration (MVR) routes packets received in a multicast source VLAN to one or more
receive VLANs. Clients are in the receive VLANs and the multicast server is in the source VLAN. Multicast routing has to be
disabled when MVR is enabled. Refer to the configuration guide at Understanding Multicast VLAN Registration for more
information on MVR. MVR is typically used for IPTV-like services and is therefore usually only available on enterprise-level
switches. Many manufacturers provide support for MVR on their high-end switches.
The main reason for using MVR is to save bandwidth by preventing duplicate multicast streams being sent in the core network,
instead the stream(s) are received on the MVR-VLAN and forwarded to the VLANs where hosts have requested it/them.
This page provides MVR related configuration. The MVR Configuration screen is shown in
