質問 9

The configuration shown in the figure is performed on R2 to filter all received routes. Suppose that there is an AS Path attribute on R1 with an AS Path attribute of [100 200 300 400] that needs to be sent to R2. Please help the network administrator to adjust the route on R1. The order of AS's in the AS Path attribute ensures that routing entries are not filtered by R2's routing policy.

（A）400

（B）200

（C）300

（D）100

質問 12

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）8888

（D）6662
