MVR multicast protocol layer 2

Multicast VLAN Registration protocol in Cisco switches deliver multicast packets received from a source VLAN to destination VLAN. Multicast routing has to be disabled when MVR is enabled. Multicast traffic can be delivered to the source VLAN by a port. This port can be work in trunk or access mode. Multicast traffic will be received from destination VLAN by a port or ports. These ports have to works in access mode only. These ports call subscribers ports.
When we want to configure MVR in a switch we have to configure in global configuration and in subscribers ports.
In the global configuration, we set up source VLAN and a  multicast group which will be transferred do the destination VLAN to the subscriber’s ports.

mvr vlan 611
mvr
mvr querytime 10
mvr mode dynamic
mvr group 232.0.2.10
mvr group 232.40.10.8
mvr group 239.40.10.8

In subscriber’s ports are configured multicast groups which we needed receive.

Parallel to the MVR protocol can work properly IGMP protocol.
