<p class="MsoNormal" style="margin-bottom:12.0pt">Hi everyone,<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Need some help in configuring Openstack nova network in Vlan mode.<o:p></o:p></p>
</div>
<p class="MsoNormal">My existing working environment:<o:p></o:p></p>
</div>
<p class="MsoNormal">1) 3 Hosts (controller1 and compute1 & compute2 nodes) with single network interface in individual host.<o:p></o:p></p>
</div>
<p class="MsoNormal">2) Was using FlatDHCPManager so far, now I've changed it to Vlan mode by following below doc:<br>
<a href="http://docs.openstack.org/grizzly/openstack-compute/admin/content/configuring-vlan-networking.html" target="_blank">http://docs.openstack.org/grizzly/openstack-compute/admin/content/configuring-vlan-networking.html</a><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">3) I've only one project "demo" and vlan102 is tagged to that.<o:p></o:p></p>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<p class="MsoNormal">Problem:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">1) Instances of the same compute1 node can talk each other but not with the instances of neighbour compute2 node.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">2) Compute1 node cannot ping/ssh to instances of their neighbor compute2 node. Whereas any instance of any compute node can reach (ping/ssh) to Compute/Controller host network and their gateway.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">My understanding is, vlan separates the network between different projects. In my case, it looks like compute nodes has been separated with their individual instances.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Could anyone please guide, what and where I'm missing?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">PS - In FlatDHCP mode, every instances can talk to each other irrespective of the hosting node and accessible from any host of the same network.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
