質問 1

In an operator's MPLS VPN network, there are two devices PE1 and PE2 for MPLSVPN data forwarding. PE1 receives a private network route of 172.16.1.0/24 from the client, and converts it to a VPNv4 route and distributes it on PE1 Released to PE2 with the label 1027. The outgoing label of the MPLS LSR-ID from PE2 to PE1 is 1025.
When a client on PE2 accesses 172.16.1.0/24, the frame sent by PE2, the inner and outer labels should be the combination of which of the following?

（A）Outer label: 1027: Inner label: 1027

（B）Outer label: 1025: Inner label: 1027

（C）Outer label, 1025: Inner label: 1025

（D）Outer label: 1027: Inner label: 1025
