MVR Configuration
To complete MVR configuration, follow these steps:
1)  Configure 802.1Q VLANs.
2)  Configure MVR globally. 
3)  Add multicast groups to MVR.
4)  Configure MVR for the ports.
5)  (Optional) Statically add ports to MVR groups. 
Configuration Guidelines
 ■ MVR does not support IGMPv3 messages.
 ■ Do not configure MVR on private VLAN ports, otherwise MVR cannot take effect.
 ■ MVR operates on the underlying mechanism of IGMP Snooping, but the two features 
operate independently of each other. Both protocols can be enabled on a port at the 
same time. When both are enabled, MVR listens to the report and leave messages only 
for the multicast groups configured in MVR. All other multicast groups are managed by 
IGMP Snooping.

4.1.1  Configuring 802.1Q VLANs
Before configuring MVR, create an 802.1Q VLAN as the multicast VLAN. Add all source 
ports (uplink ports that receive multicast data from the router) to the multicast VLAN as 
tagged ports. Configure 802.1Q VLANs for the receiver ports (ports that are connecting 
to the hosts) according to network requirements. Note that receiver ports can only belong 
to one VLAN and cannot be added to the multicast VLAN. For details, refer to Configuring 
802.1Q VLAN.
