一、基本配置

<Huawei> system-view
[Huawei] sysname AR2220-Router
[AR2220-Router] interface GigabitEthernet 0/0/0
[AR2220-Router-GigabitEthernet0/0/0] ip address 202.96.209.2 255.255.255.252
[AR2220-Router-GigabitEthernet0/0/0] undo shutdown
[AR2220-Router-GigabitEthernet0/0/0] quit

[AR2220-Router] interface GigabitEthernet 0/0/1
[AR2220-Router-GigabitEthernet0/0/1] ip address 192.168.0.1 255.255.255.0
[AR2220-Router-GigabitEthernet0/0/1] undo shutdown
[AR2220-Router-GigabitEthernet0/0/1] quit

二、NAT配置

<!-- 配置NAT基础设置 -->
[AR2220-Router] acl number 2000
[AR2220-Router-acl-basic-2000] rule permit source 192.168.0.0 0.0.0.255
[AR2220-Router-acl-basic-2000] quit

<!-- 配置Easy IP -->
[AR2220-Router] interface GigabitEthernet 0/0/0
[AR2220-Router-GigabitEthernet0/0/0] nat outbound 2000
[AR2220-Router-GigabitEthernet0/0/0] quit

<!-- 配置NAT Server -->
[AR2220-Router] interface GigabitEthernet 0/0/0
[AR2220-Router-GigabitEthernet0/0/0] nat server protocol tcp global 202.96.209.2 80 inside 192.168.0.10 8080
[AR2220-Router-GigabitEthernet0/0/0] quit

三、静态路由

<!-- 默认路由 -->
[AR2220-Router] ip route-static 0.0.0.0 0.0.0.0 202.96.209.1

<!-- 静态路由 -->
[AR2220-Router] ip route-static 192.168.10.0 255.255.255.0 192.168.0.254
[AR2220-Router] ip route-static 192.168.20.0 255.255.255.0 192.168.0.254

四、OSPF配置

[AR2220-Router] ospf 1 router-id 1.1.1.1
[AR2220-Router-ospf-1] area 0
[AR2220-Router-ospf-1-area-0.0.0.0] network 192.168.0.0 0.0.0.255
[AR2220-Router-ospf-1-area-0.0.0.0] network 10.0.0.0 0.0.0.255
[AR2220-Router-ospf-1-area-0.0.0.0] quit
[AR2220-Router-ospf-1] default-route-advertise always
[AR2220-Router-ospf-1] quit

五、DHCP配置

[AR2220-Router] dhcp enable
[AR2220-Router] ip pool LAN_POOL
[AR2220-Router-ip-pool-LAN_POOL] network 192.168.0.0 mask 255.255.255.0
[AR2220-Router-ip-pool-LAN_POOL] gateway-list 192.168.0.1
[AR2220-Router-ip-pool-LAN_POOL] dns-list 8.8.8.8 114.114.114.114
[AR2220-Router-ip-pool-LAN_POOL] lease day 7
[AR2220-Router-ip-pool-LAN_POOL] excluded-ip-address 192.168.0.1 192.168.0.50
[AR2220-Router-ip-pool-LAN_POOL] quit

[AR2220-Router] interface GigabitEthernet 0/0/1
[AR2220-Router-GigabitEthernet0/0/1] dhcp select global
[AR2220-Router-GigabitEthernet0/0/1] quit

六、保存配置

[AR2220-Router] return
<Huawei> save
The current configuration will be written to the device.

配置要点总结

• NAT：使用Easy IP简化配置，NAT Server发布内部服务
• 路由协议：OSPF适合中大型网络，静态路由适合简单环境
• DHCP：合理规划地址池，预留静态分配地址
• 安全：配合ACL实现访问控制
