Regarding the logical mode of the MPLS TTL pair, is the following description correct?

A. In the case of the MPLS VPN MPLS Ingress uniform, the private network text can be used in the reporting mode.

B. Uniform IP MPLS IP TTL 1 MPLS TTL mode is simulated. When the message passes through the network, the entry point is reduced and the field is fixed to the value.

C. MPLS TTL IP TTL MPLS A label, which has the same function as the header, can prevent the network from routing the loop (as it is)

D. Pipe IP MPLS IP TTL 1 In MPLS TTL mode, when the message passes through the network, it is mapped to the field at the ingress point.
