      <para>The OpenStack Networking service provides a scalable
    system for managing the network connectivity within an OpenStack
    cloud deployment. It can easily and quickly react to changing
    network needs (for example, creating and assigning new IP
    addresses).</para>
  <para>Networking in OpenStack is complex. This section provides the
    basic instructions for creating a network and a router. For
