Yeah, I think that's the difference. We don't do unicast flooding ("send
frames to unknown unicast destinations to every single port") because
bandwidth on the VPN is limited & more expensive.
Adding it would solve the issue at hand, but I'm not convinced that you'll
be happy with the end - it might actually end up saturating VPN links and
making users unhappy if you have "much flooded traffic" (which happens in
some of the networks).
