Multicast VLAN Registration

Multicast VLAN Registration (MVR) allows the switch to listen to the IGMP (Internet Group Management Protocol) frames. Both protocols operate independently from each other and can be enabled on the switch interfaces. In such case, MVR listens to the Join and Report messages only for the statically configured groups. All other groups are managed by IGMP snooping. MVR uses the multicast VLAN, a dedicated VLAN used to transfer multicast traffic over the network avoiding duplication of multicast streams for clients in different VLANs.
