Open Stack

Hi!
I have just deployed an OpenStack Kilo installation with DVR and expected
that it will consume one Public IP per network node as per
http://assafmuller.com/2015/04/15/distributed-virtual-routing-floating-ips/,
but it still eats one per virtual Router.
What is the correct behavior?
Otherwise, it works as a DVR should according to documentation. There are
router namespaces at both compute and network nodes, snat namespaces at the
network nodes and fip namespaces at the compute nodes. Every router has a
router_interface_distributed and a router_centralized_snat with private IPs,
however the router_gateway has a public IP, which I would like to getr id of
to increase density.
Thanks
