Mình giả lập 2 router c72000 trên GNS#, mình muốn dùng PC thật để cấu hình cho nó, mình đã kéo cloud vào và cấu hình cho f0/0 có địa chỉ cùng lớp mạng với LAN nhà mình nhưng không hiểu sao vẫn không ping được dù đã add card cho cloud. Mình nghĩ là do cái protocol down nhưng không biết cách cho nó up được. Mọi người giúp mình với!!!!!!!!!!!!
