实验1: 实验拓扑 配置步骤(在路由器上配置) (1) # 配置接口的 IP 地址。 <H3C> system-view [H3C] interface g 0/0 [[H3C-GigabitEthernet0/0]] ip address 192.168.1.254 24 [[H3C-GigabitEthernet0/0]] quit (2)# 启用 DHCP 服务。 [H3C] dhcp enable (4)# 配置 DHCP 地址池 0,采用动态绑定方式分配 IP 地址。 可分配的网段为 192.168.1.0/24,租约有效期限为 10 天,DNS 服务器地址为 192.168.1.10。 [H3C] dhcp server ip-pool 0 [H3C-dhcp-pool-0] network 192.168.1.0 mask 255.255.255.0 [H3C-dhcp-pool-0] expired day 10 [H3C-dhcp-pool-0] dns-list 192.168.1.10 [H3C-dhcp-pool-0] gateway-list 192.168.1.254 [H3C-dhcp-pool-0] quit 实验2: 实验拓扑 这个任务主要是做DHCP中继。 DHCP服务器在路由器上,而SWA上有3个VLAN,分属于3个不同网段, DHCP的请求报文是广播,因此必须在SWA上设置中继才能够传到路由器。

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 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。
