mọi người ơi giúp mình chỗ này vơi,mình định làm mô hình 2 đường truyền riêng tới 2 isp(r2,r4),mình đã trỏ ip route0.0.0.0 0.0.0.0 tới từng isp trên 2 con router r1 và r3,sau đó từ isp mình trỏ ngược lại r1 và r3 theo đó thì khi mình ping từ r1 đến f0/1 và f0/0 của r3 thì sẽ thông và ngược lại ping từ r3 đến fa0/0 và fa0/1 trên r1 đều ok đúng ko mọi người nhưng khi ping thì chỉ ping được từ r1---->r3 vẫn thông ok nhưng từ r3 đến f0/0 của r1 thì ok còn f0/1 thì không dc,mọi người giúp mình với.....file cấu hình của mình đây...
