A company consists of a head office and two branch offices, and uses MPLS VPN technology to transmit private network routes. In the networking mode of HuBandSpoke. Branches can only send and receive routes to and from the head office, and branches cannot directly send and receive routes to each other. In order to achieve the above requirements, which of the following schemes can the setting of RT be?

A. head office:Import Target 12:3; Export Targetr 3:12OBranchl:Import Target,3:12;Export Target 12:3OBranch2:Import Target: 3:12: Export Target: 12:3

B. head officeImport Target:l:l;Export Target: 3:3OBranchl:Import Targeta:3:3;Export Target: l:loBranch2:Import Target: 3:3; Export Target:2:2

C. head office:Import Target 1:1, 2:2;Export Target: 3:3OBranchl:Import Target:3:3; Export Target: l:loBranch2:ImportTarget:3:3; Export Target:2:2
