Separate Network Node with DevStack

Hi everyone!

With DevStack, there are some tutorials in which you have in a single virtual machine with all functions of OpenStack (Controller, Network and Compute).

I want to separate the network function, and use Neutron in other node (Network Node), like in the OpenStack Architecture:

What services must be activated in controller node with DevStack? In the figure, we can see that these services are Neutron Server and ML2 Plug-in, but how they are activated? How do they connect with the network node?

I suppose that is necessary to correctly configure local.conf file in controller node and in network node...

Thanks in advance!
