•Use the mvr group command to statically configure all multicast
group addresses that will join an MVR VLAN. Any multicast data
associated with an MVR group is sent from all source ports, and to all
receiver ports that have registered to receive data from that multicast
group.
The IP address range from 224.0.0.0 to 239.255.255.255 is used for
multicast streams. MVR group addresses cannot fall within the
reserved IP multicast address range of 224.0.0.x.
IGMP snooping must be enabled to a allow a subscriber to
dynamically join or leave an MVR group (see ip igmp snooping on
page 35-2). Note that only IGMP version 2 or 3 hosts can issue
multicast join or leave messages.
IGMP snooping and MVR share a maximum number of 255 groups.
Any multicast streams received in excess of this limitation will be
flooded to all ports in the associated VLAN.
Example
The following example enables MVR globally, and configures a range of
MVR group addresses:
Console(config)#mvr
Console(config)#mvr group 228.1.23.1 10
Console(config)#
