MVR for IPv4
This section describes commands used to configure Multicast VLAN Registration for
IPv4 (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 GC
mvr associated-profile Binds the MVR group addresses specified in a profile to an
MVR domain
GC
mvr domain Enables MVR for a specific domain GC
mvr priority Assigns a priority to all multicast traffic in the MVR
VLAN
GC
mvr profile Maps a range of MVR group addresses to a profile GC
mvr proxy-query-interval Configures the interval at which the receiver port sends out
general queries.
GC
mvr proxy-switching Enables MVR proxy switching, where the source port acts
as a host, and the receiver port acts as an MVR router with
querier service enabled
GC
mvr robustness-value Configures the expected packet loss, and thereby the
number of times to generate report and group-specific
queries
GC
mvr source-port-mode
dynamic
Configures the switch to only forward multicast streams
which the source port has dynamically joined
GC
mvr upstream-source-ip Configures the source IP address assigned to all control
packets sent upstream
GC
mvr vlan Specifies the VLAN through which MVR multicast data is
received
GC
mvr immediate-leave Enables immediate leave capability IC
mvr type Configures an interface as an MVR receiver or source port IC
mvr vlan group Statically binds a multicast group to a port IC
clear mvr groups dynamic Clears multicast group information dynamically learned
through MVR
PE
clear mvr statistics Clears MVR statistics PE
show mvr Shows information about MVR domain settings, including
MVR operational status, the multicast VLAN, the current
number of group addresses, and the upstream source IP
address
PE
