[Openstack-operators] Manual router setup

Conclusion. Neutron routers under Liberty (Linux Bridge) don't work.
Please prove me wrong..... Moving on to manual router creation.
1: How can I assign a fixed IP to an instance?
2: If I add routes will they get used? I probably have to create a Port
for every route (as Floating IPs do ).
------ Session: Trying to create a working router for the 15th time.
