    No, for the agents using the RPC communication there is no keystone
    authentication. This is another channel  of communication. It is
    similar to that in nova. Each of the modules is able to send one
    another messages. <br><div><div class="h5">

              Hi Ravi,<br>
              In Grizzly the L3 agent makes use of the RPC to interface
              with the Quantum plugin. In Folsom the L3 agent makes use
              of the Quantum client API to retrieve the l3 data.<br>
              Yes, there is keystone authentication. Can you please look
              at:<br>
              <a href="https://github.com/openstack/quantum/blob/stable/folsom/quantum/agent/l3_agent.py#L120" target="_blank">https://github.com/openstack/quantum/blob/stable/folsom/quantum/agent/l3_agent.py#L120</a><br>


              This is via the parameters in the INI file:<br>

                    <div>I was going through OVS agent code, found that
                      it does not authenticate with keystone, which I

              The code that you are referring to is most probably for
              the l2 agent interface.<br>
