問題 #4

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

A. Outer label: 1025: Inner label: 1027
B. Outer label: 1027; Inner label: 1027
C. Outer label: 1025; Inner label: 1025
D. Outer label: 1027; Inner label: 1025
