This example shows how to globally enable MVR and configure the global parameters:
switch# configure terminal
switch(config)# mvr
switch(config-mvr)# mvr-vlan 100
switch(config-mvr)# mvr-group 192.0.2.1 count 4
switch(config-mvr)# mvr-group 192.0.2.240/28 vlan 101
switch(config-mvr)# mvr-group 192.0.2.6 vlan 340
switch(config-mvr)# end
switch# show mvr

Purpose
Enters global configuration mode.
Globally enables MVR. The default is disabled.
Use the no form of the command to disable MVR.
Specifies the global default MVR VLAN. The MVR VLAN is the source of
the multicast message that subsequent receivers subscribe to.
The range is 1 to 4094.
Use the no form of the command to clear the MVR VLAN.
Adds a multicast group at the specified IPv4 address and (optional) netmask
length to the global default MVR VLAN. You can repeat this command to
add additional groups to the MVR VLAN.
The IP address is entered in the format a.b.c.d/m, where m is the number of
bits in the netmask, from 1 to 31.
(Optional) You can specify a number of MVR groups using contiguous
multicast IP addresses starting with the specified IP address. Use the count
keyword followed by a number from 1 to 64.
(Optional) You can explicitly specify an MVR VLAN for the group by using
the vlan keyword; otherwise, the group is assigned to the default MVR VLAN.
Use the no form of the command to clear the group configuration.
(Optional)
Returns to privileged EXEC mode.
(Optional)
Clears MVR IGMP packet counters.
(Optional)
Displays the global MVR configuration.
(Optional)
Saves the change persistently through reboots and restarts by copying the
running configuration to the startup configuration.
