[rdo-users] [tripleo] Neutron external bridge setting

I sent a similar question below to OpenStack ML last week, but haven't
got any answers yet. Since it is a TripleO related question, I am
reposting it here and hope for a better luck.
According to the TripleO documentation , the default Neutron
external bridge (NeutronExternalNetworkBridge) is left empty. This
seems to let the physical interface map to br-int instead of br-ex,
and (somehow) use more CPU power as oppose to using br-ex directly. I
don't get it... Does it mean the external traffic would go directly
from br-int to the physical interface without using br-ex? Could
someone walk me through the traffic flow in this case? I really
appreciate your help!
