OpenStack Yoga : Configure Neutron (Network Node)
2022/04/30
 
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 LinuxBridge under the backend )
