<p class="MsoNormal" style="margin-bottom:12.0pt">Yes. Just keep in mind that if you extend your configuration with a new config file, then you must change your init script / unit file to reference that file. And it would probably be a good idea to re-sync
the DB with that additional file as an option. Or you keep your plugin configuration in a single file and be happy with the current layout.<o:p></o:p></p>

<pre><br> In short, yes. If you’re connecting instances to vlan “provider” <br> networks, traffic between instances on different compute nodes <br> will traverse the “provider bridge”, get tagged out eth1, and <br> hit the physical switching fabric. Your external gateway device could also sit in that vlan, and the default route on the instance would direct external traffic to that device.<br><br> In reality, every network has ‘provider’ attributes that <br> describe the network type, segmentation id, and bridge interface <br> (for vlan/flat only). So tenant networks that leverage vlans <br> would have provider attributes set by Neutron automatically <br> based on the configuration set in the ML2 config file. If you <br><br><o:p></o:p></pre>
<pre style="margin-bottom:12.0pt">use Neutron routers that connect to both ‘tenant’ vlan-based networks and external ‘provider’ networks, all of that traffic could traverse the same provider bridge on the controller/network node, but would be tagged accordingly based on the network (ie. vlan 100 for external network, vlan 200 for tenant network).<br><br> Hope that’s not too confusing!<br><br> James<o:p></o:p></pre>
