Networking Option 1: Provider networks
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Configure the Networking components on a *compute* node.
|
|
|
|
Configure the Open vSwitch agent
|
|
--------------------------------
|
|
|
|
The Open vSwitch agent builds layer-2 (bridging and switching) virtual
|
|
networking infrastructure for instances and handles security groups.
|
|
|
|
* Edit the ``/etc/neutron/plugins/ml2/openvswitch_agent.ini`` file and
|
|
complete the following actions:
|
|
|
|
* In the ``[ovs]`` section, map the provider virtual network to the
|
|
provider physical network interface:
|
|
|
|
.. path /etc/neutron/plugins/ml2/openvswitch_agent.ini
|
|
.. code-block:: ini
|
|
|
|
[ovs]
|
|
bridge_mappings = provider:PROVIDER_INTERFACE_NAME
|
|
|
|
.. end
|
|
|
|
Replace ``PROVIDER_INTERFACE_NAME`` with the name of the underlying
|
|
provider physical network interface. See :doc:`environment-networking-ubuntu`
|
|
for more information.
|
|
|
|
* In the ``[securitygroup]`` section, enable security groups and
|
|
configure the Open vSwitch native or the hybrid iptables firewall driver:
|
|
|
|
.. path /etc/neutron/plugins/ml2/openvswitch_agent.ini
|
|
.. code-block:: ini
|
|
|
|
[securitygroup]
|
|
# ...
|
|
enable_security_group = true
|
|
firewall_driver = openvswitch
|
|
#firewall_driver = iptables_hybrid
|
|
|
|
.. end
|
|
|
|
* In the case of using the hybrid iptables firewall driver, ensure your
|
|
Linux operating system kernel supports network bridge filters by verifying
|
|
all the following ``sysctl`` values are set to ``1``:
|
|
|
|
.. code-block:: ini
|
|
|
|
net.bridge.bridge-nf-call-iptables
|
|
net.bridge.bridge-nf-call-ip6tables
|
|
|
|
.. end
|
|
|
|
To enable networking bridge support, typically the ``br_netfilter`` kernel
|
|
module needs to be loaded. Check your operating system's documentation for
|
|
additional details on enabling this module.
