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.

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
[ovs-discuss] OVS bridge absorbing ARP replies
Hi all, My network topology is host1(eth1:192.168.1.2)—(eth2:192.168.1.1)host2. I added an OVS bridge on host2 and added eth2 as a port. I configured the ip address via SDN controller. I could ping from host 1 to host2, but failed the other way. My configuration commands on host2 are: #ovs-vsctl add-br ovsbr1 #ovs-vsctl add-port ovsbr1 eth2 Then I set the ip address of ovsbr1 via SDN controller. I can ping from host1 to 192.168.1.1. But I can't ping from host 2 to host1. The reason is that host2 can't process ARP replies from host1. The result of "arp" shows that host 2 doesn't know the mac address of host1. I used tcpdump to capture the packets, it shows that ARP replies packets from are received at eth2. The result of "ovs-ofctl dump-flows ovsbr1" shows that arp replies are matched with the rule whose action is normal, I also tried to add a flow that matches the arp replies and its action is "Local". None of this works. What might be the problem? Thanks, Yuanjun ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
