21.6 MVR Overview
Multicast VLAN Registration (MVR) is designed for applications (such as Media-on-Demand
(MoD)) that use multicast traffic across an Ethernet ring-based service provider network.
MVR allows one single multicast VLAN to be shared among different subscriber VLANs on
the network. While isolated in different subscriber VLANs, connected devices can subscribe
to and unsubscribe from the multicast stream in the multicast VLAN. This improves
bandwidth utilization with reduced multicast traffic in the subscriber VLANs and simplifies
multicast group management.
MVR only responds to IGMP join and leave control messages from multicast groups that are
configured under MVR. Join and leave reports from other multicast groups are managed by
IGMP snooping.
The following figure shows a network example. The subscriber VLAN (
1 , 2 and 3 )
information is hidden from the streaming media server, S . In addition, the multicast VLAN
information is only visible to the Switch and S .

LABEL DESCRIPTION
Profile Name Enter a descriptive name for the profile for identification purposes.
To configure additional rule(s) for a profile that you have already added, enter the
profile name and specify a different IP multicast address range.
Start Address Type the starting multicast IP address for a range of multicast IP addresses that
you want to belong to the IGMP filter profile.
End Address Type the ending multicast IP address for a range of IP addresses that you want to
belong to the IGMP filter profile.
If you want to add a single multicast IP address, enter it in both the
Start Address
and End Address fields.
Add Click Add to save the profile to the Switch’s run-time memory. The Switch loses
these changes if it is turned off or loses power, so use the Save link on the top
navigation panel to save your changes to the non-volatile memory when you are
done configuring.
Clear Click Clear to clear the fields to the factory defaults.
Profile Name This field displays the descriptive name of the profile.
Start Address This field displays the start of the multicast address range.
End Address This field displays the end of the multicast address range.
