Multicast VLAN Registration Commands

This section describes commands used to configure Multicast VLAN Registration
(MVR). A single network-wide VLAN can be used to transmit multicast traffic (such
as television channels) across a service provider's network. Any multicast traffic
entering an MVR VLAN is sent to all subscribers. This can significantly reduce to
processing overhead required to dynamically monitor and establish the distribution
tree for a normal multicast VLAN. Also note that MVR maintains the user isolation
and data security provided by VLAN segregation by passing only multicast traffic
into other VLANs to which the subscribers belong.
Command
mvr

show mvr

mvr (Global Configuration)

This command enables Multicast VLAN Registration (MVR) globally on the switch,
statically configures MVR multicast group IP address(es) using the group keyword,
or specifies the MVR VLAN identifier using the vlan keyword. Use the no form of
this command without any keywords to globally disable MVR. Use the no form with
the group keyword to remove a specific address or range of addresses. Or use the
no form with the vlan keyword restore the default MVR VLAN.
Syntax
[no] mvr [group ip-address [count] | vlan vlan-id]
• ip-address - IP address for an MVR multicast group.
(Range: 224.0.1.0 - 239.255.255.255)
• count - The number of contiguous MVR group addresses.
(Range: 1-255)
• vlan-id - MVR VLAN ID (Range: 1-4094)
