🐄拓撲圖
🐄實驗環境
該拓撲圖分為四個部分最左邊位總部Tiger HQ，中間的為ISP，右上角為分部Branch1，右下角為分部Branch2。總部和分部的邊界設備用的是型號為USG 6000V的防火墻，都分別連接運營商的PE設備。總部內有vlan10和20，主機A和B屬于vlan10,主機C和D屬于vlan20。
🐄需求
-
各部分內網主機之間能夠互相聯通。
-
所有總部、分部內網主機要通過邊界防火墻能夠訪問Internet。
-
總部的主機可以訪問兩個分部的主機，兩個分部的主機也能訪問總部的主機。

1、各區域主機是否能ping通isp的服務器，可以看到總部和分部的主機都能夠ping通isp的服務器。
2、總部與分部之間的聯通測試。
可以看到總部已經可以與分部之間通訊，實驗到這里就結束了。
