Is VXLAN tunneling similar to Q-in-Q tunneling (except VxLAN works at Layer 3), such that each customer/tenant gets its own VNI and each VNI can then map to multiple VLANs, so a single VNI can encapsulate multiple VLANS. All examples on the internet give the basic configuration of 1 VLAN mapped to 1 VNI. The remote host also has the same VNI:VLAN mapping, so it receives the Layer 2 frames and forwards it on the correct VLAN.

Thanks
