Subject: [alcatel-nsp] PBB and IGMP Snooping

Hi All,

when IGMP snooping is enabled on an i-vpls instance, is it possible to activate 'send queries' towards the b-vpls?

'send-queries’  is configured under saps and sdp-bindings. On the i-vpls you can’t active send-queries to be sent to the b-vpls.
You will need a real querier.

Also, when b-vpls's FDB state changes, does it propagate to i-vpls MFIB?
i.e. If shared mac (mc-lag) to sdp mappings on b-vpls changes (via mac-notification), can that propagate into to the i-vpls MFIB??

Mac-notification sends a message with the shared sap-bmac as the source address from the new active PE, so that the remote PEs can update their FDBs. This mechanism allows to avoid black-holes for unicast traffic. For multicast traffic there is no blackhole since the traffic is flooded into the (*,G) tree… do you have any issue?
