Example Add multicast groups 225.1.2.3 -239.1.2.5 to MVR: Switch (config)# mvr group 225.1.2.3 3 19.3 mvr mode Description The mvr mode command is used to configure the MVR mode as compatible or dynamic. By default, it is compatible. To return to the default configuration, please use no mvr mode command. Syntax mvr mode { compatible | dynamic } no mvr mode Parameter compatible -- In this mode, the switch does not forward report or leave messages from the hosts to the IGMP querier. So the IGMP querier cannot learn the multicast groups membership information from the switch. You have to statically configure the IGMP querier to transmit all the required multicast streams to the switch via the multicast VLAN. dynamic -- In this mode, after receiving report or leave messages from the hosts, the switch will forward them to the IGMP querier via the multicast VLAN (with appropriate translation of the VLAN ID). So the IGMP querier can learn the multicast groups membership information through the report and leave messages, and transmit the multicast streams to the switch via the multicast VLAN according to the multicast forwarding table. 155
