Ta có một mô hình mạng thực tế như sau:
+ Mô hình có 3 nhóm, nhóm 1 và 3 mỗi nhóm gồm một Router và ba Switch lớp 2, nhóm 2 gồm 1 Switch lớp 3 và ba Switch lớp 2.
+ Cấu hình Trunk Dot1q giữa các Switch.
+ Cấu hình VTP: Mỗi nhóm giữ VTP domain là vnprox ( với x là số nhóm x = 1,2,3), VTP password là cisco, Switch x1 là Server, Switch x2,x3 là Client
+ Tạo VLAN trong từng nhóm tương ứng với hình dưới, gán cổng cho mỗi VLAN đã tạo.
+ Tiến hành định tuyến giữa các VLAN trong một nhóm và với các VLAN khác nhóm.
Tiến hành cấu hình trên các thiết bị:
