I'm running into problems with arp resolving on our five node setup where I have a full vxlan tunnel mesh between the nodes. I have a vhost-user port on compute1 and from this VM I'm trying to ping a tap port in linux namespace on controller1. All of these are in the same bridge domain. This is what happens:

• The vm sends a broadcast arp request
• The arp request arrives at the tap port on controller1, which answers as it should
• Then the arp answer is sent to compute0 instead of compute1 where is gets dropped due to this:
  • 02:28:07:200496: error-drop
      l2-fwd: Reflection Drop

I'm using vpp-17.10-rc0~157_g0117d24~b2690.x86_64 and this worked fine with 1704
