  1. BLOCK-BAD-ADDRESSES out RTB(config-router)#redistribute ospf 1 match internal metric 50 RTB(config-router)#redistribute static Ta có thể cấu hình cho RTB chỉ chèn một số mạng vào BGP thôi. Còn tất cả các route khác sẻ không được chèn vào BGP nên không đựoc quảng cáo ra ben ngoài khỏi AS. RTB(config)#router bgp 200 RTB(config-router)#neighbor 10.1.1.2 remote-as 100 RTB(config-router)#network 192.168.1.0 RTB(config-router)#network 192.168.2.0 - Trong trường hợp này chỉ có mạng 192.168.1.0 và 192.168.2.0 là được chèn vào BGP thôi. Cấu hình Thực tế 1. Cấu hình cho sơ đồ 1 Error! - Theo sơ đồ này thì ta thấy R2, R3, R4 quan hệ IBGP với nhau thuộc AS100, còn R1 thuộc AS300, R6 thuộc AS400, R5 thuộc AS200 cấu hình cho từng router một: R1#show run Building configuration...
