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 )

| [1] | Install required packages for Network Node. |
|
root@network:~# apt -y install neutron-plugin-ml2 neutron-linuxbridge-agent neutron-l3-agent neutron-dhcp-agent neutron-metadata-agent python3-neutronclient
