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.
Mô hình thực hành mô phỏng đinh tuyến VLAN
Tiến hành cấu hình trên các thiết bị:
