Hello Han/Dumitru, We tried the patch on our cluster, and we do not see the explosion of OpenFlow rules in the Integration Bridge on each of the OVN Chassis nodes. Also, on the logical switch with localnet port attached, as expected, we still have a rule to Flood the Gratuitous ARPs sent for all

Hello Dumitru, Han, So, we applied this patchset and gave it a spin on our large scale cluster and saw a significant reduction in the number of logical flows in lr_in_ip_input table. Before this patch there were around 1.6M flows in lr_in_ip_input table. However, after the patch we see about 26K

Hi Girish, I sent a patch series to implement Han's suggestion: https://patchwork.ozlabs.org/project/openvswitch/list/?series=185580 https://mail.openvswitch.org/pipermail/ovs-dev/2020-June/372005.html It would be great if you could give it a run on your setup too. Thanks, Dumitru On 6/16/20
