GS716Tv3, GS724Tv4, and GS748Tv5 Smart Switches MVR Configuration IGMP snooping helps limit multicast traffic when member ports are in the same VLAN; however, when ports belong to different VLANs, a copy of the multicast stream is sent to each VLAN that has member ports in the multicast group. MVR eliminates the need to duplicate the multicast traffic when multicast group member ports belong to different VLANs. MVR uses a dedicated multicast VLAN to forward multicast traffic over the L2 network. Only one MVLAN can be configured per switch, and it is used only for certain multicast traffic, such as traffic from an IPTV application, to avoid duplication of multicast streams for clients in different VLANs. Clients can dynamically join or leave the mutlicast VLAN without interfering with their membership in other VLANs. MVR, like IGMP snooping, allows a layer 2 switch to listen to IGMP messages to learn about multicast group membership.
