Hi all, We are having a setup where we've attached a OVS to ODL controller and 
OVS is connected. The OVS is in turn connected to Open stack and we have 
servers running in the VM.  We've configured the load balancer application in 
ODL, so that load balancing of Clients connections against Server can be 
achieved by flow rules.  When the first Client Packet is received by OVS, OVS 
forwards the packet to ODL controller. ODL controller creates rules and sends 
flow add request to OVS. Flow rules are created for both forward and reverse 
path to replace destination VIP address to chosen server IP address & 
Mac-address of the qrouter(of the next hop) . In the reverse path to replace 
the source as VIP address.   From ODL controller, we generated a packet_out for 
the initial packet with action to put on o/p port. It was observed that this 
packet was received by the OVS, but not forwarded further. We could enable 
snooping and verify that this packet was received by OVS. Also, we verified the 
counters it didn't display any drop packets.  But all subsequent packets sent 
from Client to Server are traversing through this rule and are correctly 
getting forwarded.  We also tried to modify the packet_out to go through the 
flow table rule instead of putting to the output port . Here also , we see that 
the packet was received by the OVS but was not forwarded further. Has anyone 
faced this kind of issue ? Any help is appreciated.  Regards,
Deena
