华为模拟器dhcp中继

整体思路:
1.在交换机先进行vlan的创建和划分，并且划分地址
2.在路由器打开dhcp功能，配置路由器端口地址，然后创建地址池
3.在交换机进入vlan 告示dhcp服务在哪来并开启dhcp功能
4.最后到路由器配默认路由，使路由器知道目的是交换机

LSW2：
进入端口创建vlan，并划分端口，并设置为接入模式

[Huawei]vlan batch 10 20 30
[Huawei]int g0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type access 
[Huawei-GigabitEthernet0/0/2]port default vlan 10[Huawei]int g0/0/3
[Huawei-GigabitEthernet0/0/3]port link-type access 
[Huawei-GigabitEthernet0/0/3]port default vlan 10[Huawei]int g0/0/4
[Huawei-GigabitEthernet0/0/4]port link-type access 
[Huawei-GigabitEthernet0/0/4]port default vlan 20[Huawei]int g0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type access 
[Huawei-GigabitEthernet0/0/1]port default vlan 30
//给vlan配置地址
[Huawei]int vlan 10
[Huawei-Vlanif10]ip address 192.168.10.254  24[Huawei]int vlan 20	
[Huawei-Vlanif20]ip address 192.168.20.254 24[Huawei-vlan30]int vlan 30
[Huawei-Vlanif30]ip address 192.168.30.254 24

路由器R:
进入端口全局配置

//进入端口全局配置
[Huawei]dhcp enable 
[Huawei-GigabitEthernet0/0/0]dhcp select global 
[Huawei-GigabitEthernet0/0/0] ip address 192.168.30.253 255.255.255.0 
//然后配置路由器R的地址池，但是不分配100-253的ip
[Huawei]ip pool vlan10
[Huawei-ip-pool-vlan10]network 192.168.10.0 mask 24
[Huawei-ip-pool-vlan10]gateway-list 192.168.10.254 
[Huawei-ip-pool-vlan10]excluded-ip-address 192.168.10.100 192.168.10.253
[Huawei-ip-pool-vlan10]quit
//同上步骤创建地址池 20

LSW：

//进入vlan 告示dhcp服务在哪来并开启dhcp功能
[Huawei]dhcp enable
[Huawei]int vlan 10	
[Huawei-Vlanif10]dhcp select relay 
[Huawei-Vlanif10]dhcp relay server-ip 192.168.30.253
[Huawei-Vlanif10]quit
//同上进入vlan20告示dhcp服务在哪

最后到路由器配默认路由：

[Huawei]ip route-static 0.0.0.0 0.0.0.0 192.168.30.254
