Configuring the ML2 networking plugin

Before you can build network resources in an OpenStack cloud, a network plugin must be defined and configured. The ML2 plugin provides a common framework that allows multiple drivers to interoperate with one another. In this section, we will look at how to configure the Linux bridge ML2 driver and agent on the controller01 and compute01 hosts.

Note

Configuring the Linux bridge and Open vSwitch drivers for simultaneous operation will be discussed in this book but may not be appropriate for a production environment. To make things simple, I recommend deploying the Linux bridge driver if distributed virtual routers are not required. The configuration and architecture of distributed virtual routers are outlined in Chapter 12, Distributed Virtual Routers.
