Overview

Data networks are used to model the L2 Networks that nodes' data, pci-sriov and
|
|
pci-passthrough interfaces attach to.
|
|
|
|
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.

.. xbooklink VXLAN Data Networks are specific to |prod-os| application 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:`Add Segmentation Ranges Using
|
|
the CLI <adding-segmentation-ranges-using-the-cli>`.
