Hi Eric,

Actually i am following your guide/pdf based on page 17 and after the 
vlans were created as example you type the ip addr and brctl show to 
make sure the bridges and vlans have been created, i guess it just 
applies to the admin tenant, is it right? because i noticed that if i 
add in --project_id the id of the Admin Tenant the bridge and vlan is 
created immediately but if I add another project id it is not created.

Thanks in advance,

Omar L.
