OpenStack Newton : Configure Neutron#3 ( Control Node )2017/07/03 |

Configure OpenStack Network Service (Neutron).
This example is not All in One Settings like here, but Configure the 3 Nodes environment like follows.
Neutron needs a plugin software, it's possible to choose it from some softwares. This example chooses ML2 plugin. ( it uses Open vSwitch under the backend )
