<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>
