DHCP中继配置案例
作者:互联网
需求:在不同网段获取IP地址
- Router为DHCP服务器,开启DHCP服务,为PC分配地址,使用地址池网段为192.168.1.0/24,
- 地址池中排除掉地址192.168.1.254,192.168.1.253 ,这些地址留作他用
- 为客户端分配的网关地址是:192.168.1.254,分配租期为2天。DNS服务器地址为:8.8.8.8
- SW上部署两个VLAN;分别是VLAN10,VLAN20,PC属于VLAN10,Router属于VLAN20
- 要求PC机器能够通过DHCP自动获取IP地址和网关。
实现步骤
-
交换机配置vlan
<Huawei>sys [Huawei]sys SW # 将 1端口划分 vlan10 24端口划分vlan 20 [SW]vlan batch 10 20 [SW]int g0/0/1 [SW-GigabitEthernet0/0/1]port link-type access [SW-GigabitEthernet0/0/1]port default vlan 10 [SW-GigabitEthernet0/0/1]int g0/0/24 [SW-GigabitEthernet0/0/24]port link-type access [SW-GigabitEthernet0/0/24]port default vlan 20 [SW-GigabitEthernet0/0/24]int vlanif 10 [SW-Vlanif10]ip address 192.168.1.254 24 [SW-Vlanif10]int vlanif 20 [SW-Vlanif20]ip address 192.168.2.1 24

路由器配置地址池
<Huawei>sys [Huawei]sys Router [Router]int g0/0/0 [Router-GigabitEthernet0/0/0]ip address 192.168.2.2 24 # 启动dhcp服务 # 创建地址池 [Router]dhcp enable [Router]ip pool dhcppool #命名为 dhcppool [Router-ip-pool-dhcppool]dns-list 8.8.8.8 #dns 设置 # 设置网关 [Router-ip-pool-dhcppool]gateway-list 192.168.1.254 # 分配网段 [Router-ip-pool-dhcppool]network 192.168.1.0 mask 24 # 排除分配,预留他用 [Router-ip-pool-dhcppool]excluded-ip-address 192.168.1.250 192.168.1.253 # 设置租期2天 [Router-ip-pool-dhcppool]lease day 2 [Router-ip-pool-dhcppool]dis this [V200R003C00] # ip pool dhcppool gateway-list 192.168.1.254 network 192.168.1.0 mask 255.255.255.0 excluded-ip-address 192.168.1.250 192.168.1.253 lease day 2 hour 0 minute 0 dns-list 8.8.8.8 # return # 进入端口0 ,启用dhcp 地址池 [Router]int g0/0/0 [Router-GigabitEthernet0/0/0]dhcp select global # 返程路由 [Router]ip route-static 192.168.1.0 24 192.168.2.1

交换机DHCP中继
[SW]dhcp enable [SW]int vlanif 10 [SW-Vlanif10]dhcp select relay #中继服务器地址 可以把192.168.2.2 地址池的地址分配给PC1 # 从192.168.2.2 地址池拿IP [SW-Vlanif10]dhcp relay server-ip 192.168.2.2
