In case of multi-node setup, we should configure the networking agent in the compute node to work with the neutron server on the controller. You should repeat the steps in this session when you decide to add an additional compute node to the existing OpenStack environment.
As I mentioned earlier, for all-in-one node setup, we can merge the controller and compute node components in a single node. So, do follow the instructions on the same node to install and configure the neutron compute node components:
apt install neutron-linuxbridge-agent -y
By now, you should have neutron agent packages installed in your compute node. Now, simply copy and paste the crudini commands in the terminal to ...
