• Question 418:

  Which of the following statements is TRUE concerning a VPRN data plane flow?

  A. A data packet will receive a service label at the CE and a transport label at the ingress PE.

  B. A data packet intended for a remote CE will have its service label swapped at each P router along the path towards the egress PE.

  C. At the egress PE, the transport label will be popped and the data packet forwarded with the service label.
