    Cấu hình Frame Relay chia SuB Interface trong Dynamip !!!

    Mô hình HUB & SPOKE :



    File .NET :


    ghostios = True
    autostart = False

    [localhost]

    [[2691]]
    image = C:\Program Files\Dynamips\images\C2691-AD.BIN
    ram = 128


    [[ROUTER SG]]
    model = 2691
    mmap = True
    s1/0 = F1 1
    idlepc = 0x60ab2a14


    [[ROUTER HN]]
    model = 2691
    mmap = True
    s1/0 = F1 2
    idlepc = 0x60aadd74


    [[ROUTER CT]]
    model = 2691
    mmap = True
    s1/0 = F1 3
    idlepc = 0x60aadf68


    [[FRSW F1]]

    1:100 = 2:200
    1:300 = 3:400

    1. Cấu hình Hub Router sử dụng 1 Sub Interface Multipoint để giao tiếp với các Spoke Router :

    Đặt IP :

    SG(config-subif)#no ip split-horizon
