Hi All, I have launched 2 VMs on OVS. The OVS is done set-controller to our OF controller. I have added ARP redirect flows on the OVS.
When I did ping between VM1 and VM2, the ARP packet came to OF controller as PACKET_IN and controller has send PACKET_OUT message and added a unicast flow with in-port and dl_dst to output:VM2 port. The ICMP echo req packet has come to VM2. I expected the VM2 to send ICMP echo reply which would be a packet miss in OVS as there is no associated flow. Instead VM2 also sent an ARP request for VM1 and I could see this in our OF controller. Can't VM2 just use the srcMAC in ICMP echo req instead of sending ARP again ?? My question might be naive but I thought it would help me in getting my basics right. Thanks Rahul
