Actually my provider network is externally routable :)  It's not an
'external network' because the router isn't in OpenStack it's in my
normal network hardware and we don't provide floating IPs.  So while
in practice it's an external network using public v4 addressing if you
examine it in neutron it is not 'external'.

The use case is connecting OpenStack VMs to existing datacenter VLANs
that also include non-OpenStack systems.
