5.25.5 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.
