      ProxyARP issue observed in VPP version 19.04.1-release in kubernetes deployment (Contiv-VPP). Does not occur on VPP 19.01 release.

       

      VPP config, packet trace and counters attached.  Interesting bit:

      00:24:23:058844: arp-input
      request, type ethernet/IP4, address size 6/4
      08:00:27:02:85:01/192.168.16.100 -> 00:00:00:00:00:00/192.168.16.150
      00:24:23:058861: error-drop
      rx:GigabitEthernet0/8/0
      00:24:23:058863: drop
      arp-input: ARP replies sent

      Seems like the responses are sent, "ARP replies sent" counter is incremented, but tx counter on the interface does not increment, and tcpdump on the ARP request sender shows no response received.
