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

• A.Outer label: 1027, inner label: 1025
• B.Outer label: 1027, inner label: 1027
• C.Outer label: 1025, inner label: 1027
• D.Outer label: 1025, inner label: 1025
