Made paths to include files relative to doc source. This is needed for downstream builds and is good practice for reusability. Fixed some include statements with broken syntax. Added missing section labels to include file.

Data Networks in OpenStack Overview
|
|
===================================
|
|
|
|
Data networks are used to model the L2 Networks that nodes' data, pci-sriov
|
|
and pci-passthrough interfaces attach to.
|
|
|
|
.. note::
|
|
|
|
Data networks are required if you plan to deploy the openstack application
|
|
or provide SR-IOV network interface access to container workloads.
|
|
|
|
A Layer 2 physical or virtual network or set of virtual networks is used to
|
|
provide the underlying network connectivity needed to support the application
|
|
project networks. Multiple data networks may be configured as required, and
|
|
realized over the same or different physical networks. Access to external
|
|
networks is typically granted to the **openstack-compute** labeled worker nodes
|
|
using the data network. The extent of this connectivity, including access to
|
|
the open internet, is application dependent.
|
|
|
|
Data networks are created at the |prod| level. Flat, VLAN and VXLAN type
|
|
data networks are supported by the |prod-os| virtual switch. For details on
|
|
creating data networks and assigning them to node interfaces, see the
|
|
following documentation:

VXLAN Data Networks are specific to |prod-os| application.
|
|
|
|
.. xreflink and are described in detail in :ref:`VXLAN Data Networks
|
|
<vxlan-data-networks>`.
|
|
|
|
Segmentation ID ranges for VLAN and VXLAN data networks are defined through
|
|
OpenStack Neutron commands, see :ref:`Adding Segmentation Ranges Using the CLI
|
|
<adding-segmentation-ranges-using-the-cli>`.
