FWaaS was retired with [1], so it's time to remove the misleading references from doc as well. [1]: https://review.opendev.org/c/openstack/neutron-fwaas/+/735829 Change-Id: Ic098263b7450c09308eeff4ef6dd2f8097c0a449

Introduction

The OpenStack Networking service (neutron)
|
|
provides an API that allows users to set up and define network connectivity
|
|
and addressing in the cloud. The project code-name for Networking services is
|
|
neutron. OpenStack Networking handles the creation and management of a virtual
|
|
networking infrastructure, including networks, switches, subnets, and
|
|
routers for devices managed by the OpenStack Compute service
|
|
(nova). Advanced services such as firewalls or virtual private network (VPN)
|
|
can also be used.
|
|
|
|
OpenStack Networking consists of the neutron-server, a database for
|
|
persistent storage, and any number of plug-in agents, which provide
|
|
other services such as interfacing with native Linux networking
|
|
mechanisms, external devices, or SDN controllers.
|
|
|
|
OpenStack Networking is entirely standalone and can be deployed to a
|
|
dedicated host. If your deployment uses a controller host to run
|
|
centralized Compute components, you can deploy the Networking server
|
|
to that specific host instead.
|
|
|
|
OpenStack Networking integrates with various OpenStack
|
|
components:
|
|
|
|
* OpenStack Identity service (keystone) is used for authentication
|
|
and authorization of API requests.
|
|
|
|
* OpenStack Compute service (nova) is used to plug each virtual
|
|
NIC on the VM into a particular network.
|
|
|
|
* OpenStack Dashboard (horizon) is used by administrators
|
|
and project users to create and manage network services through a web-based
|
|
graphical interface.
|

.. note::
|
|
|
|
The network address ranges used in this guide are chosen in accordance with
|
|
`RFC 5737 <https://tools.ietf.org/rfc/rfc5737>`_ and
|
|
`RFC 3849 <https://tools.ietf.org/html/rfc3849>`_, and as such are restricted
|
|
to the following:
|
|
|
|
**IPv4:**
|
|
|
|
* 192.0.2.0/24
|
|
* 198.51.100.0/24
|
|
* 203.0.113.0/24
|
|
|
|
**IPv6:**
|
|
|
|
* 2001:DB8::/32
|
|
|
|
The network address ranges in the examples of this guide should not be used
|
|
for any purpose other than documentation.

To reduce clutter, this guide removes command output without relevance
