Microstack and VLAN

Hi everyone!
I am new to this forum, so correct me if I am not clear enough.
I have installed it correctly microstack and managed to make it work with any CIDR for flat external networks thanks to this wonderful tutorial.

However, I was wondering if there’s a way to make this setup work with VLAN.
I have tried to configure it but it did not work. I think because Openstack Neutron is missing the correct ml2 plugin.
Can somebody help me?
Thanks.
