<p class="MsoNormal"><font color="#000000">We are setting up a 4 node setup
(1 Controller node, 2 Compute Nodes (CN1, CN2), 1 Network Node) to view ML2
functionality on Havana. We are trying the following use cases to understand
its functionality.</font></p>
<p class="MsoNormal"><font color="#000000"> </font></p>
<p class="MsoNormal"><font color="#000000"><b>Note on Controller node
configuration</b>: We have set the following
ML2 configuration:</font></p><p class="MsoNormal"><font color="#000000"><br></font></p>

<p class="MsoNormal"><font color="#000000">In this scenario, we would like to know the agents that needs to be run on Network Node (NN) – Is it OVS agent OR linuxbridge?</font></p><p class="MsoNormal"><font color="#000000"><br>
</font></p><p class="MsoNormal"><font color="#000000">We have heard people talking that both the agents cannot run concurrently on the NN. So, how can we accomplish the above use cases if only one </font></p><p class="MsoNormal">
<font color="#000000">agent is allowed to run on the NN. </font></p><p class="MsoNormal"><font color="#000000"><br></font></p><p class="MsoNormal"><font color="#000000"><br></font></p><p class="MsoNormal"><span style="color:rgb(0,0,0)">Is there any other configuration settings that needs to be done to enable it?

</p><p class="MsoNormal"><font color="#000000"><br></font></p><p class="MsoNormal">Also, please let us know is there any documentation or guide available for ML2 configuration on CentOS or RHEL , because it seems the packages for ML2 available in EPEL repo is not stable which make the neutron-server dead after configuring ML2.</p>

Alternatively , it would be great if we could get the debian packages for ubuntu as soon as possible.( ml2 missing) </p><p class="MsoNormal"><a href="http://ubuntu-cloud.archive.canonical.com/ubuntu/dists/precise-updates/havana/main/binary-amd64/Packages">http://ubuntu-cloud.archive.canonical.com/ubuntu/dists/precise-updates/havana/main/binary-amd64/Packages</a> </p>
