None of this works. You could try to tcpdump the ovsbr1 where the IP address is and see if the ARP packets are getting there. It sounds like a firewall issue. -- Flavio ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
Re: [ovs-discuss] OVS bridge absorbing ARP replies
Hi Flavio, Thanks for your reply. I might misconfigured OVS bridge. I forgot to remove the IP address from the original interface, that might caused the problem.
