Reproduce Steps:

Clean installation of Openstack Liberty wrt http://docs.openstack.org/liberty/install-guide-ubuntu/ and http://docs.openstack.org/liberty/install-guide-ubuntu/neutron-controller-install-option1.html

Looks like this is similar with https://bugs.launchpad.net/nova/+bug/1488537

Rushikesh have you setup l3 agent? From the http://docs.openstack.org/liberty/install-guide-ubuntu/neutron-controller-install-option1.html, it didn't mention about l3 agent. If you didn't setup l3 agent, just will be the case same with 1488537.

[Rushikesh (rushikesh7)]

Hi Alex, I have not installed L3 agent and have disabled the L3 agent option from Openstack UI 'enable_router': False
I'm using ML2 plugin with pure flat network option.

I do not see that the issue is related to 1488537, it may be related, i'm not sure.

[Alex Xu (xuhj)]

Rushikesh, thanks for the reply, as this patch https://review.openstack.org/#/c/216746/, it mentioned the neutron will return 404 when l3 agent isn't enabled. So I think this bug is similar to https://bugs.launchpad.net/nova/+bug/1488537

[Rushikesh (rushikesh7)]

Thanks Alex,
I see the status on the patch as "Review in Progress", is there any way where in I can update that to my Ubuntu Liberty Setup and confirm the fix ?
