The configuration supports one flat or multiple VLAN provider networks. For
|
|
simplicity, the following procedure creates one flat provider network.
|
|
|
|
#. Source the administrative project credentials.
|
|
#. Create a flat network.
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack network create --share --provider-physical-network provider \
|
|
--provider-network-type flat provider1

The ``share`` option allows any project to use this network. To limit
|
|
access to provider networks, see :ref:`config-rbac`.

|
|
To create a VLAN network instead of a flat network, change
|
|
``--provider-network-type flat`` to ``--provider-network-type vlan``
|
|
and add ``--provider-segment`` with a value referencing the VLAN ID.
|

Enabling DHCP causes the Networking service to provide DHCP which can
|
|
interfere with existing DHCP services on the physical network
|
|
infrastructure. Use the ``--no-dhcp`` option to have the subnet managed
|
|
by existing DHCP services.

.. note::
|
|
|
|
The Networking service uses the layer-3 agent to provide router
|
|
advertisement. Provider networks rely on physical network infrastructure
|
|
for layer-3 services rather than the layer-3 agent. Thus, the physical
|
|
network infrastructure must provide router advertisement on provider
|
|
networks for proper operation of IPv6.
