Learning OpenStack Networking - Third Edition

Defining an interface driver

Just like the previously installed agents, the Neutron LBaaS v2 agent must be configured to use an interface driver that corresponds to the chosen networking driver. In this configuration, there are two options:

• Linux bridge
• Open vSwitch

Update the Neutron LBaaS agent configuration file node at /etc/neutron/lbaas_agent.ini on the controller to use one of the following drivers.

For Linux bridge:

[DEFAULT]...interface_driver = linuxbridge 

For Open vSwitch:

[DEFAULT]...interface_driver = openvswitch 

In this book, we specified that the controller node runs the Linux bridge agent. Therefore, the LBaaS v2 agent should be configured to use the Linux bridge interface driver.
