配置步骤
(1) # 配置路由器。
<H3C> system-view
[H3C] interface g 0/0
[[H3C-GigabitEthernet0/0]] ip address 10.1.1.2 30
[[H3C-GigabitEthernet0/0]] quit

启用 DHCP 服务。

[H3C] dhcp enable

配置 DHCP 地址池 1，为来自 192.168.1.0/24网段内的客户端分配地址。

[H3C] dhcp server ip-pool 1
[H3C-dhcp-pool-0] network 192.168.10.0 mask 255.255.255.0
[H3C-dhcp-pool-0] dns-list 8.8.8.8
[H3C-dhcp-pool-0] gateway-list 192.168.10.254
[H3C-dhcp-pool-0] quit

配置 DHCP 地址池 2，为来自 192.168.20.0/24网段内的客户端分配地址。

[H3C] dhcp server ip-pool 2
[H3C-dhcp-pool-0] network 192.168.20.0 mask 255.255.255.0
[H3C-dhcp-pool-0] dns-list 8.8.8.8
[H3C-dhcp-pool-0] gateway-list 192.168.20.254
[H3C-dhcp-pool-0] quit

配置 DHCP 地址池 3，为来自 192.168.30.0/24网段内的客户端分配地址。

[H3C] dhcp server ip-pool 3
[H3C-dhcp-pool-0] network 192.168.30.0 mask 255.255.255.0
[H3C-dhcp-pool-0] dns-list 8.8.8.8
[H3C-dhcp-pool-0] gateway-list 192.168.30.254
[H3C-dhcp-pool-0] quit

配置静态路由到192.168.0.0/16网段

[H3C]ip route-static 192.168.0.0 16 10.1.1.1
(2)# 配置 SWA交换机。

建立vlan，并且配置各接口的 IP 地址。

<H3C> system-view
[H3C]vlan 10
[H3C-vlan10]quit
[H3C]vlan 20
[H3C-vlan20]quit
[H3C]vlan 30
[H3C-vlan30]quit

[H3C]inter range g 1/0/1 to g 1/0/5
[H3C-if-range]port link-type access
[H3C-if-range]port access vlan 10
[H3C-if-range]quit
[H3C]inter range g 1/0/6 to g 1/0/10
[H3C-if-range]port link-type access
[H3C-if-range]port access vlan 20
[H3C-if-range]quit
[H3C]inter range g 1/0/11 to g 1/0/15
[H3C-if-range]port link-type access
[H3C-if-range]port access vlan 30
[H3C-if-range]quit

[H3C]inter vlan 10
[H3C-Vlan-interface10]ip add 192.168.10.254 24
[H3C-Vlan-interface10]quit
[H3C]inter vlan 20
[H3C-Vlan-interface20]ip add 192.168.20.254 24
[H3C-Vlan-interface20]quit
[H3C]inter vlan 30
[H3C-Vlan-interface30]ip add 192.168.30.254 24
[H3C-Vlan-interface30]quit
[H3C]
[H3C]inter g 1/0/23
[H3C-GigabitEthernet1/0/23]port link-m r
[H3C-GigabitEthernet1/0/23]ip add 10.1.1.1 30
[H3C-GigabitEthernet1/0/23]quit
(3)#配置DHCP中继（SWA交换机）

启用 DHCP 服务。

[H3C] dhcp enable

配置 VLAN 接口 10 工作在 DHCP 中继模式。

[H3C] interface vlan-interface 10
[H3C-Vlan-interface10] dhcp select relay

配置 DHCP 服务器的地址。

[H3C-Vlan-interface10] dhcp relay server-address 10.1.1.2
[H3C-Vlan-interface10] quit

配置 VLAN 接口 20 工作在 DHCP 中继模式。

[H3C] interface vlan-interface 20
[H3C-Vlan-interface20] dhcp select relay
[H3C-Vlan-interface20] dhcp relay server-address 10.1.1.2
[H3C-Vlan-interface20] quit

配置 VLAN 接口 30 工作在 DHCP 中继模式。

[H3C] interface vlan-interface 30
[H3C-Vlan-interface30] dhcp select relay
[H3C-Vlan-interface30] dhcp relay server-address 10.1.1.2
[H3C-Vlan-interface30] quit
