1. Create cluster and download settings for cluster
fuel deployment --env 1 --default

2.On controller and compute add in quantum_settings: L2: phys_nets: following strings
     physnet3:
       bridge: br-prv3
       vlan_range: 1000:1030
and to network_scheme: transformations: following
 - name: br-prv3
   provider: ovs
   action: add-br
3. Upload settings:
fuel deployment --env 1 --upload
4. Deploy cluster
5. Check /etc/neutron/plugins/ml2/ml2_conf.ini

Good output for step 5:
root@node-1:~# cat /etc/neutron/plugins/ml2/ml2_conf.ini | grep physnet3
physical_network_mtus =physnet3:1500,physnet2:1500,physnet1:1500
network_vlan_ranges =physnet3:1040:1050,physnet2:1000:1030,physnet1
bridge_mappings=physnet3:br-prv3,physnet2:br-prv,physnet1:br-floating
