There is one thing , which I clearly see . It is qrouter-namespace misconfiguration. There is no qr-xxxxx bridge attached to br-int
Picture , in general, should look like this
ubuntu@ubuntu-System:~$ sudo ip netns exec qrouter-6cb93ddd-2637-449d-8b10-7c07da49ee8c route -n

I would also advise you to post a question also on ask.openstack.org
