[pox-dev] ARP in L2_learning

[Talal Alharbi]

Dear All, 

Running a test on L2_learning module and trying to send an ARP packet from a host using Scapy. After sending an ARP request from host#1 to host#2,  I checked Wireshark and I have found 4 packets: 

1- Broadcast ARP request  
2- Unicast ARP reply 
3- Unicast ARP request 
4- Unicast ARP reply

Why  do I have the third packet? Who is sending it ?  I used scapy command: arp = ARP(op=1, psrc=host1, pdst=host2, hwdst= mac address of host2)
Cheers, 
Talal
