If one set of VLANs is for external networks which are created by admins,
why even specify network_vlan_ranges for that set?

For example, even if network_vlan_ranges is 'local:1000:4000', you can
still successfully run the following as an admin:
neutron net-create --provider:network_type=vlan
--provider:physical_network=local --provider:segmentation_id=40 myextnet
--router:external
