Packstack Newton configuration with VLAN interface
Hello,
I am trying to install a Packstack Newton in my LAB and I am having a big problem with the network because I don't understand how it should be configured the physical network.
So, I am using Packstack Newton, installed in Centos 7.3. I have 3 servers (1 controller with 2 computes) I am attaching a image to have a better understanding of the scenario.
The idea is that I can't figure out how the physical interface, that will be connected in the external bridge, should be configured.
All the interfaces for controller and computers are connected in a HP Switch that has the ports in trunk mode. I need to use VLAN 150. I have the interface em1 used for management and configured with VLAN in em1.150
The problems that I have is how to configure the physical interface em2: 1. Should I create em2.150 and add the VLAN and IP details and create the external network as a flat network? How should I have the answer file in this case? or 2.Should I let the interface unconfigured and create the external network from openstack as a VLAN network?

Thanks in advance, Razvan
If tenants (say 10 ) are segregated via VLAN IDs (10 -20 ) then Switch connecting Compute and Controller Node should have ports in trunk mode accepting vlan IDs 10,..,20. Say external network has VLAN ID 150. Another ports on switch should be tuned to to provide traffic tagged 150.
Having external vlan tag among tenat's segregating interval doesn't look to me as a good idea
