模擬及地址劃分

設(shè)計(jì)一個(gè)單位的網(wǎng)絡(luò)，分為三個(gè)部門，地址如下：

部門名

IP地址

子網(wǎng)掩碼

網(wǎng)關(guān)

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(shè)計(jì)一個(gè)單位的服務(wù)器網(wǎng)絡(luò)，分為2個(gè)服務(wù)器，地址如下：

服務(wù)器名

IP地址

子網(wǎng)掩碼

網(wǎng)關(guān)

服務(wù)A

18.20.19.2

255.255.255.0

19.29.19.1

服務(wù)B

18.20.19.3

255.255.255.0

19.29.19.1

規(guī)劃不同部門及服務(wù)器在不同的網(wǎng)段，將其分在不同的vlan下面，主要是為了隔離廣播風(fēng)暴，提高網(wǎng)速。然后通過核心交換機(jī)進(jìn)行數(shù)據(jù)交換。

三、拓?fù)浣Y(jié)構(gòu)圖

拓?fù)浣Y(jié)構(gòu)圖如上，地址分配也已經(jīng)在圖上展現(xiàn)，接下來就是配置了。

四、各個(gè)設(shè)備配置

配置核心交換機(jī)

先分VLAN，如下圖：

再配置各個(gè)接口類型，如下圖：

然后配置各個(gè)vlan的網(wǎng)關(guān)。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

六、結(jié)語

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