質問 3：
As shown in the figure, Site1 and Site2 need to achieve mutual access through the operator's BGP/MPLS IPVPN. It is known that the public network tunnel between PE1 and PE2 has been established (the label information is shown in the figure), and PE1 has advertised the route of network segment 192.168.1.0/24 in Site1 to PE2 through the MPLS BGP neighbor relationship, and the route learning is normal.
When grabbing between P and PE1, when Site2 accesses the 192.168.1.0/24 data of Site1, what should be the outermost label?
A. 6661
B. 3
C. 6662
D. 8888
正解：D
