VLAN实验报告

一、实验拓扑

二、实验要求

1.全网可达，

2.使用DHCP获取IP地址。

三、实验思路与步骤

步骤一：

划分网段，左边有vlan2、3，右边有vlan2、3，对应路由四个接口的四个网段

192.168.1.0/24---左边vlan3

192.168.2.0/24---左边vlan2

192.168.3.0/24---右边vlan3

192.168.4.0/24---右边vlan2

步骤二：

配置交换机

创建VLAN：

[Huawei]vlan batch 2 3

进入PC机与交换机连接的线路接口配置access，以第一台交换机为例：
[Huawei]int e0/0/2
[Huawei-Ethernet0/0/2]port link-type access 
[Huawei-Ethernet0/0/2]port default vlan 2
[Huawei-Ethernet0/0/2]int e0/0/3
[Huawei-Ethernet0/0/3]port link-type access
[Huawei-Ethernet0/0/3]port default vlan 3

进入交换机与交换机/路由器连接的线路接口配置trunk，以第一台交换机为例：
[Huawei-Ethernet0/0/3]int e0/0/1
[Huawei-Ethernet0/0/1]port link-type trunk 

[Huawei-Ethernet0/0/1]port trunk allow-pass vlan 2 3

步骤三：

配置路由器

<Huawei>sys
Enter system view, return user view with Ctrl+Z.

先给四个子接口配个IP地址：
[Huawei]int g0/0/0.2
[Huawei-GigabitEthernet0/0/0.2]ip add 192.168.1.1 24
[Huawei-GigabitEthernet0/0/0.2]int g0/0/0.1
[Huawei-GigabitEthernet0/0/0.1]ip add 192.168.2.1 24
[Huawei-GigabitEthernet0/0/0.1]int g0/0/1.2
[Huawei-GigabitEthernet0/0/1.2]ip add 192.168.3.1 24
[Huawei-GigabitEthernet0/0/1.2]int g0/0/1.1
[Huawei-GigabitEthernet0/0/1.1]ip add 192.168.4.1 24

进入每个接口后还要分别：

配置子接口管理的vlan2  /  vlan3

[Huawei-GigabitEthernet0/0/0.1]dot1q termination vid 2

[Huawei-GigabitEthernet0/0/0.2]dot1q termination vid 3

开启ARP广播响应

[Huawei-GigabitEthernet0/0/0.1]arp broadcast enable

再配个DHCP自动分配地址：

[Huawei]dhcp enable

[Huawei]ip pool 1
Info: It's successful to create an IP address pool.
[Huawei-ip-pool-1]network 192.168.1.0 mask 24
[Huawei-ip-pool-1]gateway-list 192.168.1.1
[Huawei-ip-pool-1]dns-list 114.114.114.114 8.8.8.8
[Huawei-ip-pool-1]int g0/0/0.2
[Huawei-GigabitEthernet0/0/0.2]dhcp select global 

[Huawei]ip pool 2
Info: It's successful to create an IP address pool.
[Huawei-ip-pool-2]network 192.168.2.0 mask 24   
[Huawei-ip-pool-2]gateway-list 192.168.2.1
[Huawei-ip-pool-2]dns-list 114.114.114.114 8.8.8.8
[Huawei-ip-pool-2]int g0/0/0.1
[Huawei-GigabitEthernet0/0/0.1]dhcp select global

[Huawei]ip pool 3
Info: It's successful to create an IP address pool.
[Huawei-ip-pool-3]network 192.168.3.0 mask 24
[Huawei-ip-pool-3]gateway-list 192.168.3.1
[Huawei-ip-pool-3]dns-list 114.114.114.114 8.8.8.8

[Huawei]int g0/0/1.2
[Huawei-GigabitEthernet0/0/1.2]dhcp select global

[Huawei-ip-pool-3]ip pool 4
Info: It's successful to create an IP address pool.
[Huawei-ip-pool-4]network 192.168.4.0 mask 24
[Huawei-ip-pool-4]gateway-list 192.168.4.1
[Huawei-ip-pool-4]dns-list 114.114.114.114 8.8.8.8
[Huawei]int g0/0/1.1
[Huawei-GigabitEthernet0/0/1.1]dhcp select global

然后别忘了启动PC端的DHCP协议：

检测一下：

PC1

PC2

PC5

PC1测试全网可达：

第一台交换机：

第二台交换机：

第三台交换机：
