Re: [openstack-dev] [octavia] amphora fails to send request to members

Yipei, Yeah, we have clearly identified the problem. Those two default route lines should not be different. See my devstack: sudo: unable to resolve host amphora-20a717b4-eb97-4b5c-a11a-0633fe61f135 default via 10.0.0.1 dev eth1 table 1 onlink default via 10.0.0.1 dev eth1 onlink So the issue

Hi, Michael, Please ignore my last two mails. Sorry about that. The results of the two commands are as follows. ubuntu@amphora-a0621f0e-d27f-4f22-a4ee-05b695e2b71f:~$ sudo ip netns exec amphora-haproxy ip route show table all sudo: unable to resolve host

Hi, Michael, Sorry about the typo in the last mail. Please just ignore the last mail. In the environment where octavia and tricircle are installed together, I created a router and attached subnet1 to it. Then I bind the mac address of 10.0.1.10 (real gateway) to ip of 10.0.1.1 in the amphora arp

Re: [openstack-dev] [octavia] amphora fails to send request to members

Hi, Michael, I tried to run to command, and I think the amphora can connect to the member (10.0.1.3). The results are as follows. ubuntu@amphora-a0621f0e-d27f-4f22-a4ee-05b695e2b71f:~$ sudo ip netns exec amphora-haproxy ping 10.0.1.3 sudo: unable to resolve host

The actual gateway address does not matter to Octavia/amphora. It gets that value from DHCP or from neutron if a static address was assigned from neutron. My concern is that the subnet gateway 10.0.1.10 does not match the gateway address DHCP gave us 10.0.1.1. Technically, since the two addresses

Re: [openstack-dev] [octavia] amphora fails to send request to members

Hi, Michael, Thanks a lot for your reply. I can make sure that there is no router or multiple dhcp services in my environment. As shown in my first mail, the haproxy in the amphora tries to find the gateway ip 10.0.1.1 that does not exist in the environment.
