1、拓扑图

 2、汇聚交换机设置

sys# 关闭消息提示
[Huawei]undo in en[Huawei]sys SW1# 批量创建 VLAN

[SW1-Vlanif30]ip addr 192.168.30.1 24

3、SW2 交换机设置

sys
[Huawei]undo in en
[Huawei]sys SW2
[SW2]vlan 10
[SW2-vlan10]int e0/0/1
[SW2-Ethernet0/0/1]p l a
[SW2-Ethernet0/0/1]p d v 10
[SW2-Ethernet0/0/1]int e0/0/2
[SW2-Ethernet0/0/2]p l t
[SW2-Ethernet0/0/2]p t a v a

4、SW3 交换机设置

sys
[Huawei]undo in en
[Huawei]sys SW3
[SW3]vlan 20
[SW3-vlan20]int e0/0/1
[SW3-Ethernet0/0/1]p l a
[SW3-Ethernet0/0/1]p d v 20
[SW3-Ethernet0/0/1]int e0/0/2
[SW3-Ethernet0/0/2]p l t
[SW3-Ethernet0/0/2]p t a v a

5、SW10 交换机设置

sys
[Huawei]undo in en
[Huawei]sys SW10
[SW10]vlan 100
[SW10-vlan100]int e0/0/2
[SW10-Ethernet0/0/2]p l a
[SW10-Ethernet0/0/2]p d v 100
[SW10-Ethernet0/0/2]int e0/0/3
[SW10-Ethernet0/0/3]p l a
[SW10-Ethernet0/0/3]p d v 100
[SW10-Ethernet0/0/3]int e0/0/1
[SW10-Ethernet0/0/1]p l t
[SW10-Ethernet0/0/1]p t a v a

6、R1 路由器设置

sys
[Huawei]undo in en
[Huawei]sys R1
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip addr 192.168.30.2 24# 设置静态路由
[R1-GigabitEthernet0/0/0]ip route-static 192.168.0.0 255.255.0.0 192.168.30.1

Cloud1 桥接设置

 7、DHCP 服务器设置

（1）创建一台虚拟机，网络选择 "仅主机模式"，并关闭DHCP

（2）宿主机网卡

（3）DHCP服务器IP设置

IP：192.168.100.254/24，网关192.168.100.1 

（3）DHCP服务器 测试网络连通

 （5） DHCP服务器创建3个作用域

先添加 192.168.10.0/24 网段

添加地址范围，因为 192.168.10.1 已经被网关占用了，所以从 2 开始

一直下一步至，添加网关

后面一直到完成，在依次添加其它2个网段，如下图
