config>service>pw-template>igmp-snooping
Description This command defines the maximum number of multicast groups that can be joined on this SAP or
SDP. If the node receives an IGMP join message that would exceed the configured number of groups,
the request is ignored.
Default no max-num-groups
Parameters count — Specifies the maximum number of groups that can be joined on this SAP or SDP.
mrouter-port
Syntax [no] mrouter-port
Context config>service>vpls>sap>igmp-snooping
config>service>vpls>spoke-sdp>igmp-snooping
config>service>vpls>mesh-sdp>igmp-snooping
Description This command specifies whether a multicast router is attached behind this SAP.
Configuring a SAP or SDP as an mrouter-port will have a double effect. Firstly, all multicast traffic
received on another SAP or SDP will be copied to this SAP or SDP. Secondly, IGMP reports
generated by the system as a result of someone joining or leaving a multicast group, will be sent to
this SAP or SDP.
If two multicast routers exist in the network, one of them will become the active querier. While the
other multicast router (non-querier) stops sending IGMP queries, it should still receive reports to keep
its multicast trees up to date. To support this, the mrouter-port should be enabled on all SAPs or SDPs
connecting to a multicast router.
Note that the IGMP version to be used for the reports (v1or v2) can only be determined after an initial
query has been received. Until such time no reports are sent on the SAP or SDP, even if mrouter-port
is enabled.
If the send-queries command is enabled on this SAP, the mrouter-port parameter can not be set.
Default no mrouter-port
mvr
Syntax mvr
Context config>service>vpls>igmp-snooping
