The optimization that OVS does should only affect cases where a MAC would otherwise quickly bounce back and forth between a number of learned ports. Is there anything unusual in your setup? Can you reproduce this with a simple setup? _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
