1、一、搭建本次实验的环境
四台路由器、两台交换机，由于模拟器本身的问题，所以用路由器当做PC
2、二、配置本次实验的IP地址
R1 10.0.12.0/24 1.1.1.1/32
R2 10.0.12.0/24 10.10.10.1/24
R3 192.168.1.1/24
配置命令在这里不赘述
3、三、配置R4的DHCP客户端
[Huawei]sysname R4[R4]dhcp enable[R4]interface GigabitEthernet 0/0/1[R4-GigabitEthernet0/0/1] ip address dhcp-alloc
4、四、配置R1与R2的路由
[R1]ospf 1[R1-ospf-1]area 0[R1-ospf-1-area-0.0.0.0]network 1.1.1.1 0.0.0.0[R1-ospf-1-area-0.0.0.0]network 10.0.12.0 0.0.0.255[R2]ospf 1[R2-ospf-1]silent-interface GigabitEthernet 0/0/1[R2-ospf-1]area 0[R2-ospf-1-area-0.0.0.0]network 10.10.10.0 0.0.0.255[R2-ospf-1-area-0.0.0.0]network 10.0.12.0 0.0.0.255
5、五、配置IP的地址池
[R1]ip pool DHCP[R1-ip-pool-DHCP]gateway-list 10.10.10.1 [R1-ip-pool-DHCP]network 10.10.10.0 mask 255.255.255.0 [R1-ip-pool-DHCP]excluded-ip-address 10.10.10.2 10.10.10.10 [R1-ip-pool-DHCP]dns-list 1.1.1.1[R1-ip-pool-DHCP]lease day 3[R3]ip pool DHCP[R3-ip-pool-DHCP]gateway-list 192.168.1.1 [R3-ip-pool-DHCP]network 192.168.1.0 mask 255.255.255.0 [R3-ip-pool-DHCP]excluded-ip-address 192.168.1.2 192.168.1.10 [R3-ip-pool-DHCP]dns-list 192.168.1.1[R3-ip-pool-DHCP]lease day 3
6、六、配置R2的DHCP中继，关闭R3的端口，让R4学习R1的DHCP
[R2]dhcp enable [R2]dhcp server group DHCP[R2-dhcp-server-group-DHCP]dhcp-server 10.0.12.1[R2-dhcp-server-group-DHCP]quit[R2]interface GigabitEthernet 0/0/1[R2-GigabitEthernet0/0/1]dhcp select relay[R2-GigabitEthernet0/0/1]dhcp relay server-select DHCP
7、七、查看R4的端口情况和R4到R1的网络状况
dis int ip g0/0/1
ping 1.1.1.1
<R4>ping 1.1.1.1 PING 1.1.1.1: 56 data bytes, press CTRL_C to break Reply from 1.1.1.1: bytes=56 Sequence=1 ttl=254 time=100 ms Reply from 1.1.1.1: bytes=56 Sequence=2 ttl=254 time=80 ms Reply from 1.1.1.1: bytes=56 Sequence=3 ttl=254 time=100 ms Reply from 1.1.1.1: bytes=56 Sequence=4 ttl=254 time=100 ms Reply from 1.1.1.1: bytes=56 Sequence=5 ttl=254 time=90 ms
