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 the 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.
