Installing and configuring the Neutron L3 agent

To install the Neutron L3 agent, run the following command on the controller01 node:

# apt install neutron-l3-agent 

Neutron stores the L3 agent configuration in the /etc/neutron/l3_agent.ini file. The most common configuration options will be covered in the following subsections.

Defining an interface driver

The Neutron L3 agent must be configured to use an interface driver that corresponds to the chosen mechanism driver. In a reference implementation, that can be either the Linux bridge or Open vSwitch drivers. In this environment, the linux bridge driver will be installed on controller01.

On the controller01 node, update the Neutron L3 agent configuration file at /etc/neutron/l3_agent.ini and specify the following Linux bridge interface driver for this particular environment:

[DEFAULT]
...
interface_driver = linuxbridge

 

 

For your reference, the following can be used when the network node hosting routers is configured for Open vSwitch:

[DEFAULT...
