mrouter-port
Syntax [no] mrouter-port
Context config>service>vpls>sap>snooping
config>service>vpls>spoke-sdp>snooping
config>service>vpls>mesh-sdp>snooping
Description
This command specifies whether a multicast router is attached behind this SAP or SDP.
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 (v1, v2 or v3) can only be determined after an
initial query has been received. Until such time no reports are sent on the SAP or spoke SDP, even if
mrouter-port is enabled.
This parameter can only be enabled on a SAP or spoke SDP, not on a mesh SDP.
If the send-queries command is enabled on this SAP or spoke SDP, the mrouter-port parameter can
not be set.
Default
no mrouter-port
mvr
Syntax mvr
Context config>service>vpls>snooping

query-interval
Syntax query-interval seconds
no query-interval
Context config>service>vpls>snooping
config>service>vpls>sap>snooping
config>service>vpls>spoke-sdp>snooping
config>service>vpls>mesh-sdp>snooping
Description
If the send-queries command is enabled, this parameter specifies the interval between two
consecutive general queries sent by the system on this SAP or SDP.
The configured query-interval must be greater than the configured query-response-interval.
