<para>Configuring Networking can be one of the most bewildering experiences
you will encounter when working with OpenStack. To assist in this we have
chosen the simplest production-ready configuration for this guide: the legacy
networking in OpenStack Compute, with a flat network, that takes care of DHCP
and is made highly available by splitting across multiple hosts.</para>

<para>This setup uses "multi-host" functionality: the networking is configured to be highly
available by splitting networking functionality across multiple hosts. As a result, there is no
single network controller that acts as a single point of failure. Because each compute node is
configured for networking in this setup, no additional networking configuration is required on
the controller.</para>
