模擬及地址劃分

設計一個單位的網絡，分為三個部門，地址如下：

部門名

IP地址

子網掩碼

網關

部門A

19.20.20.*

255.255.255.0

19.29.20.1

部門B

19.20.21.*

255.255.255.0

19.29.21.1

部門C

19.20.22.*

255.255.255.0

19.29.22.1

設計一個單位的服務器網絡，分為2個服務器，地址如下：

服務器名

IP地址

子網掩碼

網關

服務A

18.20.19.2

255.255.255.0

19.29.19.1

服務B

18.20.19.3

255.255.255.0

19.29.19.1

規劃不同部門及服務器在不同的網段，將其分在不同的vlan下面，主要是為了隔離廣播風暴，提高網速。然后通過核心交換機進行數據交換。

三、拓撲結構圖

拓撲結構圖如上，地址分配也已經在圖上展現，接下來就是配置了。

四、各個設備配置

PART

配置核心交換機

先分VLAN，如下圖：

再配置各個接口類型，如下圖：

然后配置各個vlan的網關。如下圖：

[Huawei]clear configuration int g0/0/1 //由于之前配置失誤，這里清除一下配置

Warning: All configurations of the interface will be cleared, and its state will

be shutdown. Continue? [Y/N] :y

Info: Total execute 2 command(s), 2 successful, 0 failed.

[Huawei]int g0/0/1

六、結語

通過以上配置，就可以完成一個較為高級的局域網配置了，大部分中等局域網都是這么配置的，這樣的配置也適用大多網絡。你們看懂了嗎？
