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.
