需求：现有两台电脑需要AR5路由器来分配IP地址 实现：先为路由器的各个接口配好IP地址 给AR5路由器设置个IP route 并测试能否ping通1.254这个网关，测试OK 然后回到视图模式，给DHCP授权 建立网段池，并取个名字 给这池子加网段，子网掩码，网关，DNS 然后回到接口把DHCP设置为全局模式 再回到AR4授权并把0接口设置为中继线路模式 指明DHCP服务器IP地址 然后把PC设置为DHCP就OK了 AR4路由器 <Huawei>system-view [Huawei]interface GigabitEthernet 0/0/0 [Huawei-GigabitEthernet0/0/0]ip address 192.168.1.254 [Huawei]interface GigabitEthernet 0/0/1 [Huawei-GigabitEthernet0/0/1]ip address 192.168.2.1 24 [Huawei]dhcp enable [Huawei-GigabitEthernet0/0/0]dhcp select relay [Huawei-GigabitEthernet0/0/0]dhcp relay server-ip 192.168.2.2 AR5路由器 <Huawei>system-view [Huawei]interface GigabitEthernet 0/0/0 [Huawei-GigabitEthernet0/0/0]ip address 192.168.2.2 24 [Huawei-GigabitEthernet0/0/0]dhcp select global [Huawei]ip route-static 192.168.1.0 24 192.168.2.1 [Huawei]dhcp enable [Huawei]ip pool a [Huawei-ip-pool-a]network 192.168.1.0 mask 24 [Huawei-ip-pool-a]gateway-list 192.168.1.254 [Huawei-ip-pool-a]dns-list 8.8.8.8 [Huawei-GigabitEthernet0/0/0]dhcp select global
