Hi,

I wonder if it is possible to use 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 does 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:

|[ml2_type_vlan]
network_vlan_ranges 
=provider0,provider1,tenant-vlan2:200:299,tenant-vlan3:300:399

[ovs]
bridge_mappings 
=provider0:br-ext0,provider1:br-ext1,tenant-vlan2:br-vlan2,tenant-vlan3:br-vlan3|

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

Thanks,
Vladislav
