24.6 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 OLT and S.
Figure 46 MVR Network Example
igmp-filtering profile <name>
start-address <ip> end-address
<ip>
Sets the range of multicast address(es) in a profile.
name: 1-32 alphanumeric characters
no igmp-filtering profile <name>
Removes the specified IGMP filtering profile. You cannot delete
an IGMP filtering profile that is assigned to any ports.
no igmp-filtering profile <name>
start-address <ip> end-address
<ip>
Clears the specified rule of the specified IGMP filtering profile.
show interfaces config <aid>
igmp-filtering
Displays IGMP filtering settings.
aid: slot-<slot> | <ge|xe|pon>-<slot>-<port>
interface port-channel <aid>
Enters config-interface mode for the specified port(s).
igmp-filtering profile
<name>
Assigns the specified IGMP filtering profile to the port(s). If IGMP
filtering is enabled on the OLT, the port(s) can only join the
multicast groups in the specified profile.
no igmp-filtering profile
Prohibits the port(s) from joining any multicast groups if IGMP
filtering is enabled on the OLT.
