CLI
– This example configures profile number 19 by setting the access mode to
“permit” and then specifying a range of multicast groups that a user can join. The
current profile configuration is then displayed.
Multicast VLAN Registration
Multicast VLAN Registration (MVR) is a protocol that controls access to a single
network-wide VLAN most commonly used for transmitting multicast traffic (such as
television channels or video-on-demand) across a service provider’s network. Any
multicast traffic entering an MVR VLAN is sent to all attached subscribers. This
protocol can significantly reduce to processing overhead required to dynamically
monitor and establish the distribution tree for a normal multicast VLAN. This makes
it possible to support common multicast services over a wide part of the network
without having to use any multicast routing protocol.
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.
Even though common multicast streams are passed onto different VLAN groups
from the MVR VLAN, users in different IEEE 802.1Q or private VLANs cannot
exchange any information (except through upper-level routing services).
