Which of the following regarding MPLS encapsulation for VPRN services is TRUE?
In the context of MPLS encapsulation for Virtual Private Routed Networks (VPRN) services, the customer's Layer 2 header is removed at the ingress Label Edge Router (iLER). VPRN services involve Layer 3 VPN technology, which means that the Layer 2 header is stripped off before the packets enter the MPLS network for appropriate routing. Therefore, the correct answer is that the customer's Layer 2 header is removed at the iLER.
The answer should be B : The customer's Layer 2 header is removed at the iLER.
Why? It is a VPRN Service (Layer 3 Service).
