Provider Networks

Provider networks allow to connect compute instances directly to physical networks avoiding tunnels. This is necessary for example for some performance critical applications. Only administrators of OpenStack can create such networks. For provider networks compute hosts must have external bridge created and configured by Ansible tasks like it is already done for tenant DVR mode networking. Normal tenant non-DVR networking does not need external bridge on compute hosts and therefore operators don’t need additional dedicated network interface.

To enable provider networks, modify the /etc/kolla/globals.yml file as the following example shows:

enable_neutron_provider_networks: "yes"
