<div class="gmail_default" style="font-family:tahoma,sans-serif">when IGMP snooping is enabled on an i-vpls instance, is it possible to activate 'send queries' towards the b-vpls?</div>

</div>
<div>'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.</div>
<div>You will need a real querier.</div>

<div class="gmail_default" style="font-family:tahoma,sans-serif">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??</div>

</div>
<div>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?</div>
