Comment 1 for bug 1789434

So I did a little debugging here.

DVR router (router1)
$ openstack router set --disable router1
All ports (3) showed in DOWN state

$ openstack router set --ha router1
$ openstack router set --enable router1
All ports showed in ACTIVE state

$ openstack router set --disable router1
All ports still in ACTIVE state

Any future attempt to disable the router always showed ports ACTIVE, even if I changed it back to non-ha, so it was permanently broken.

Created a new router, just DVR (router2) - it was fine - could disable/enable and see ports change state.

The fact that the ports got "stuck" would point to an issue on the server-side.
