As shown in the figure, in the hub&spoke multicast mode of MPLS bgp VPN, in order to realize that the branch can only communicate with the headquarters, the branches cannot communicate with each other. Which of the following schemes can the RT be set?
A. Headquarters: Import Target: 12:3 Export Target: 12:3 Branch 1: Import Target: 12:3 Export Target: 12:3 Branch 2: Import Target: 12:3 Export Target: 12:3
B. Headquarters: Import Target: 1:1 Export Target: 3:3 Branch 1: Import Target: 3:3 Export Target: 1:1 Branch 2: Import Target: 3:3 Export Target: 2:2
C. Headquarters: Import Target: 2:2 Export Target: 3:3 Branch 1: Import Target: 3:3 Export Target: 1:1 Branch 2: Import Target: 3:3 Export Target: 2:2
D. Headquarters: Import Target: 12:3 Export Target: 3:12 Branch 1: Import Target: 3:12 Export Target: 12:3 Branch 2: Import Target: 3:12 Export Target: 12:3
Answer:D
