Node set up: OVS plug-in

	Note
	This section also applies to the ML2 plug-in when Open vSwitch is used as a mechanism driver.

If you use the Open vSwitch plug-in, you must install Open vSwitch and the neutron-plugin-openvswitch-agent agent on each data-forwarding node:

	Warning
	Do not install the openvswitch-brcompat package because it prevents the security group functionality from operating correctly.

Procedure 7.9. To set up each node for the OVS plug-in

Install the OVS agent package. This action also installs the Open vSwitch software as a dependency:
```
# apt-get install neutron-plugin-openvswitch-agent
```
On each node that runs the neutron-plugin-openvswitch-agent, complete these steps:
- Replicate the ovs_neutron_plugin.ini file that you created on the node.
- If you use tunneling, update the ovs_neutron_plugin.ini file for the node with the IP address that is configured on the data network for the node by using the local_ip value.
Restart Open vSwitch to properly load the kernel module:
```
# service openvswitch-switch restart
```

Restart the agent:

# service neutron-plugin-openvswitch-agent restart

All nodes that run neutron-plugin-openvswitch-agent must have an OVS br-int bridge. To create the bridge, run:
```
# ovs-vsctl add-br br-int
```
