Refer to the exhibit.
Which statement is true?
A.
There is an MPLS network that is running 6PE, and the ingress PE router has no mpls ip propagatettl.
B.
There is an MPLS network that is running 6VPE, and the ingress PE router has no mpls ip
propagate-ttl.
C.
There is an MPLS network that is running 6PE or 6VPE, and the ingress PE router has mpls ip
propagate-ttl.
D.
There is an MPLS network that is running 6PE, and the ingress PE router has mpls ip propagate-ttl.
E.
There is an MPLS network that is running 6VPE, and the ingress PE router has mpls ip propagatettl.
second line shows MPLS IPV6 or IPV6 vrf,
Left “mpls ip propagate-ttl”, if enable the trace route will show internal hops in the mpls.
so C is correct.
