Described configuration module specifically for, the importing route target RT parameter of the first virtual private networks forwarding instance VRF and derivation RT parameter are set to the first parameter and the second parameter respectively, and issue the virtual private network VPN routing iinformation of a described VRF, wherein, a described VRF is VRF corresponding with X2 business on described CSG, described first parameter is converted to according to the first transformation rule by the IP address of described base station, and described second parameter is converted to according to the second transformation rule by the IP address of base station, described opposite end; And receive the VPN routing iinformation of the 2nd VRF that described opposite end CSG sends over, described 2nd VRF is VRF corresponding with X2 business on described opposite end CSG, importing RT parameter in the VPN routing iinformation of described 2nd VRF is converted to according to described second transformation rule by the IP address of base station, described opposite end, and the derivation RT parameter in the VPN routing iinformation of described 2nd VRF is converted to according to described first transformation rule by the IP address of described base station; Or

Described configuration module specifically for, group attribute in the derivation RT parameter of the one VRF and Border Gateway Protocol label B GP Label route updating packet is set to the 3rd parameter, wherein, a described VRF is VRF corresponding with X2 business on described CSG, and described 3rd parameter is obtained by the IP address transition of described base station; And send the VPN routing iinformation of a described VRF and described BGP Label route updating packet to the Border Gateway Protocol (BGP) neighbor device connecting described CSG; And send virtual private networks route egress filtering request VPN ORF message and Border Gateway Protocol exit port route filtering request BPG ORF message to described bgp neighbor equipment, importing RT optimum configurations in wherein said VPN ORF message is the 4th parameter, group attribute in described BPG ORF message is set to described 4th parameter, and described 4th parameter is obtained by the IP address transition of base station, described opposite end; Receive VPN routing iinformation and the BGP Label routing iinformation of the transmission of described bgp neighbor equipment, wherein, after described VPN routing iinformation and described BGP Label routing iinformation are respectively the described VPN ORF message and BGPORF message that described bgp neighbor device parses receives, obtain described 4th parameter, and by the VPN routing iinformation that sends after described 4th parameter and its local routing information successful match and BGP Label routing iinformation.
