Devstack multi-node neutron setup with multiple interfaces and VLAN tenant networks

This is my network topology:

Openstack management network - 192.168.132.1/24
Public network - 10.21.13.160/27
Physnet1 - 192.168.142.1/24 with VLAN range 3200-3299
Physnet2 - 192.168.152.1/24 with VLAN range 3300-3399

The inter-VM traffic is supposed to run on the physnets.

I have 2 compute nodes and 1 controller node, and I want to setup Openstack using devstack with neutron networking. I have read through every tutorial I have found but none seem to apply for my scenario. Is it even possible to set it up this way with devstack? I'm a bit doubtful of having VM traffic running over 2 networks, if it's not possible to do then how would I set it up using only one of them, for example Physnet1?

If someone could guide me through how to configure the local.conf files for the controller and the computes I would appreciate it a lot.
