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>

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>

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
feel is a security concern.</div>

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