Ah, ok, this is the point. What I would like to have instead is

1) one big external network with routable, private IPs, to be used by *any*
   tenant (where any tenant can plug ports)

2) one external network with public IPs, to be used as floating IPs
   (where tenants cannot plug ports)

3) small external networks dedicated to a tenant

You are only implementing 3), and it should work on Juno.

I will take a look at the bug.
