Plug-ins typically have requirements for particular
software that must be run on each node that handles data
packets. This includes any node that runs nova-compute and nodes
that run dedicated OpenStack Networking service agents
such as neutron-dhcp-agent,
neutron-l3-agent,
neutron-metering-agent or
neutron-lbaas-agent.
A data-forwarding node typically has a network interface with an IP address on the “management network” and another interface on the “data network”.
This section shows you how to install and configure a
subset of the available plug-ins, which might include the
installation of switching software (for example, Open
vSwitch) and as agents used to communicate with the
neutron-server process running elsewhere
in the data center.
