MVR for IPv4

MVR FOR IP V 4
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 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 Configures an interface as a static member of an MVR
group which is forwarded from the MVR VLAN to the
specified interface within the receiver VLAN
IC
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
show mvr associated-
profile
Shows the profiles bound the specified domain PE
show mvr interface Shows MVR settings for interfaces attached to the MVR
VLAN
PE
show mvr members Shows information about the current number of
entries in the forwarding database, or detailed
information about a specific multicast address
