EGISTRATION
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 Function Mode
mvr Globally enables MVR, statically configures MVR group GC
address(es), or specifies the MVR VLAN identifier
mvr immediate-leave Enables immediate leave capability IC
mvr type Configures an interface as an MVR receiver or source IC
port
mvr vlan group Configures an interface as a static member of an MVR IC
group which is forwarded from the MVR VLAN to the
specified interface within the receviever VLAN
