<div>
<p class="MsoNormal">Hello.<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'm looking for the way of LinuxBridge setup for openstack neutron networking instead of ML2 VLAN/VXLAN/GRE like your reason, and you seems successfully deployed the environment. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Could you give me any advice for the deployment?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'm now deploying openstack 3 nodes (actually, I attached another compute, so my current deployment setup is 4nodes, i.e., 1 controller, 1 network, and 2 computes) by following the openstack installation guide, <a href="http://docs.openstack.org/kilo/install-guide/install/yum/content/neutron-controller-node.html">http://docs.openstack.org/kilo/install-guide/install/yum/content/neutron-controller-node.html</a>.
I think several options in /etc/nova/nova.conf, /etc/neutron/plugins/ml2/ml2_conf.ini and /etc/neutron/neutron.conf should be modifed properly in order to use LinuxBridge instead of OVS. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Here are the lists what I know to modify:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">1. /etc/neutron/neutron.conf on controller<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">core_plugin = ml2 (I think this should be modified but I don't know what parameter indicates Linux Bridge Agent Plugin)<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">2. /etc/neutron/plugins/ml2/ml2_conf.ini on controller<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Do I still need to modify this file? I'm confused, because the file name is 'ml2', which is for ml2 plugin not for 'linux bridge'... And, I wonder the lists should be modified.<o:p></o:p></p>
