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.
TABLE 110 Multicast VLAN Registration for IPv4 Commands
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-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 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
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
PE
show mvr profile Shows all configured MVR profiles PE
show mvr statistics Shows MVR protocol statistics for the specified interface PE
