Tiếp theo ta sẻ sử dụng suppress-map trong aggregate route

Các route nằm trong route map đều bị đánh giấu là chử

s

Tức nó sẻ không được quảng bá ra AS bên ngoài

Ta sẻ cấu hình cho R1 chỉ cho phếp quảng cáo route 192.168.192.0 ,192.168.193.0,192.168.194.0 còn tất cả các route còn lại đều bị suppress không được quảng cáo

ra bên ngoài

Tương tự đối với R5 chỉ được quảng cáo mạng

192.168.196.0, 192.168.197.0,192.168.198.0

Còn route 192.168.195.0 và 192.168.199.0 sẻ không được quảng cáo ra bên ngoài bởi các router trong AS
