Hi Justin, That's good my understanding is correct.
Although OVS doesn't support IGMP snooping, could I know what underlying mechanism in OVS result in "VM-B would not receive the multicast traffic joined by VM-A"?

The effect like Openvswitch has already supported IGMP > snooping/query. Is there anything we have missed? You are correct that OVS doesn't support IGMP snooping. The behavior you were expecting is the behavior I would have expected. --Justin _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
