I wonder how it is possible to setup multiple network interfaces / 
bridge mappings for VLAN tenants and providers at the same time. E.g. in 
case of 1 VLAN network for tenant and 1 external VLAN how should neutron 
bridge mapping work? User interface does not allow to specify the mapping.

Example: 2 external VLAN interfaces and 2 tenant ones. In this case 
neutron configuration would be:

network_vlan_ranges = 

bridge_mappings = 

How can neutron decide on choosing correct vlan mapping for tenant? Will 
it try to pick provider0 if normal user creates a tenant network?


PS. Similar question could not be answered in [openstack]
