Selected Answer: B
In this design, the loopback addresses of the enterprise CE (Customer Edge) routers are the only addresses advertised to the service provider cloud network. This is achieved by utilizing MPLS to encapsulate the VPNv4 label and VPN payload, ensuring that only the loopback addresses are advertised. The transport layer carrying the VPNv4 label and VPN payload is achieved using the MP-BGP control plane, meeting the requirement of carrying the VPNv4 label and payload over the MP-BGP control plane. By utilizing multipoint GRE, the transport layer is not under the control of the service provider, fulfilling the requirement of the transport layer not being under service provider control.
