OpenStack Pike : Configure Neutron#3 (Control Node)2017/09/04 |
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 )
