<p class="MsoNormal" style="margin-bottom:12.0pt">vlan id maps to the segmentation-id of the network. Later when you create a subnet under a network the subnet is associated to the vlan-id(segmentation-id) of its network.<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">So all you have to do is provide '--provider:segmentation-id' param while creating network. I am not sure with the exact param name, though it should be something like what I have mentioned. I do not have access
to my OpenStack, but you can look it up using 'neutron net-create --help'. I am not sure if the dashboard allows you to do this, so use the cli. Finally make sure you do this as 'admin' user.

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Hi All,<br>
<br>
I have, step by step, followed the OpenStack icehouse installation guide to install control, compute and neutron nodes. They all run fine like OpenStack document describes. There is a GRE tunneling connection described in OpenStack installation guide from compute
nodes to a neutron node. We currently plan to change the GRE tunneling connection to vlan, but I don't see the Openstack installation describes detail for setting up vlan.<br>
<br>
I can see the type driver need to be changed from gre to vlan in ml2_conf.ini files in all nodes. I also got a HP switch configured vlan trunk ports for each computer and neutron systems to replace the current flat switch in the physical private connection.<br>
<br>
Besides the above mentioned ml2_conf.ini change and physical connection change, is there anything else I need to do for setting the vlan connection to get the external/internal nets, subnets and the router to work again to build instances? I am going to do
this work very soon and will appreciate advices from your experience.<br>
<br>
Thank you,<br>
Mitchell<br>
