MVR Commands
Internet Group Management Protocol (IGMP) Layer 3 is widely used for IPv4 network
multicasting. In Layer 2 networks, IGMP uses resources inefficiently. For example, a Layer 2
switch multicast traffic to all ports, even if there are receivers connected to only a few ports.

To address this problem, the IGMP Snooping protocol was developed. The problem still
appears, though, when receivers are in different VLANs.

MVR is intended to solve the problem of receivers in different VLANs. It uses a dedicated
manually configured VLAN, called the multicast VLAN, to forward multicast traffic over a
Layer 2 network with IGMP snooping.
