OpenStack Yoga : Configure Neutron (Control Node)2022/05/31 |
|
Configure OpenStack Network Service (Neutron).
This example is not on the 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. It chooses ML2 plugin on this example. ( it uses Open vSwitch under the backend )
