ENSP小练习
作者：互联网
要求：1.全网可达；2.PC5和PC2需要动态路由配置DHCP，3.客服端可以接受到服务端的信息，4.R5和R1有换回路由5.R6，R5，R6互相之间不能设置下一跳直连（练习是我自己编的，使用使用指定路由网段，后面会修改）
首先配置路由器（R1,R4,R5,R6）：
//R1
<Huawei>SYS
Enter system view, return user view with Ctrl+Z.
[Huawei]SYSN R1
[R1]interface g0/0/1
[R1-GigabitEthernet0/0/1]ip address 4.0.0.2 24
Nov 12 2021 12:29:17-08:00 R1 %%01IFNET/4/LINK_STATE(l)[3]:The line protocol IP
on the interface GigabitEthernet0/0/1 has entered the UP state.
[R1-GigabitEthernet0/0/1]int g0/0/2
[R1-GigabitEthernet0/0/2]ip address 1.0.0.2 24
Nov 12 2021 12:30:07-08:00 R1 %%01IFNET/4/LINK_STATE(l)[4]:The line protocol IP
on the interface GigabitEthernet0/0/2 has entered the UP state.
[R1-GigabitEthernet0/0/2]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add
[R1-GigabitEthernet0/0/0]ip address 2.0.0.2 24
Nov 12 2021 12:30:37-08:00 R1 %%01IFNET/4/LINK_STATE(l)[5]:The line protocol IP
on the interface GigabitEthernet0/0/0 has entered the UP state.
[R1-GigabitEthernet0/0/0]q
//R4
<Huawei>SYS
Enter system view, return user view with Ctrl+Z.
[Huawei]SYSN R4
[R4]inter
[R4]interface g0/0/0
[R4-GigabitEthernet0/0/0]ip address 4.0.0.1 24
//R6
<Huawei>SYS
Enter system view, return user view with Ctrl+Z.
[Huawei]SYSN R6
[R6]interface g0/0/0
[R6-GigabitEthernet0/0/0]ip address 2.0.0.1 24
[R6]interface g0/0/1
[R6-GigabitEthernet0/0/1]ip address 3.0.0.1 24
//R5
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]SYSN R5
[R5]interface g0/0/1
[R5-GigabitEthernet0/0/1]ip address 5.0.0.1 24
Nov 12 2021 12:27:47-08:00 R5 %%01IFNET/4/LINK_STATE(l)[1]:The line protocol IP
on the interface GigabitEthernet0/0/1 has entered the UP state.
[R5-GigabitEthernet0/0/1]int g0/0/0
[R5-GigabitEthernet0/0/0]ip address 1.0.0.1 24
Nov 12 2021 12:28:06-08:00 R5 %%01IFNET/4/LINK_STATE(l)[2]:The line protocol IP
on the interface GigabitEthernet0/0/0 has entered the UP state.
[R5-GigabitEthernet0/0/0]q然后开始配置DHCP： (DHCP的四个过程见前文)
//R4
[R4-GigabitEthernet0/0/1]ip address 192.168.3.1 24
Nov 12 2021 14:00:58-08:00 R4 %%01IFNET/4/LINK_STATE(l)[1]:The line protocol IP
on the interface GigabitEthernet0/0/1 has entered the UP state.
//我这里出了问题，没有先配置网络接口就先设置了HCDP（顺序已改正）
[R4]dhcp enable
Info: The operation may take a few seconds. Please wait for a moment.done.
[R4]ip pool daibi
Info: It's successful to create an IP address pool.
[R4-ip-pool-daibi]network 192.168.3.0 ?
mask Mask
<cr> Please press ENTER to execute command
[R4-ip-pool-daibi]network 192.168.3.0 mask 24
[R4-ip-pool-daibi]gateway-list 192.168.3.1
[R4-ip-pool-daibi]dns-list 144.144.144.144 8.8.8.8
[R4-ip-pool-daibi]q
[R4]inter
[R4]interface g0/0/1
[R4-GigabitEthernet0/0/1]dhcp select global
[R4-GigabitEthernet0/0/1]q
//R6
[R6-GigabitEthernet0/0/1]ip address 192.168.5.1 24
Nov 12 2021 14:00:58-08:00 R4 %%01IFNET/4/LINK_STATE(l)[1]:The line protocol IP
on the interface GigabitEthernet0/0/1 has entered the UP state.
[R6]dhcp enable
Info: The operation may take a few seconds. Please wait for a moment.done.
[R6]ip pool shabi
Info: It's successful to create an IP address pool.
[R6-ip-pool-shabi]network 192.168.5.0 mask 24
[R6-ip-pool-shabi]gateway-list 192.168.5.1
[R6-ip-pool-shabi]dns-list 144.144.144.144
[R6-ip-pool-shabi]q
[R6]interface g0/0/2
[R6-GigabitEthernet0/0/2]dhcp select global
[R6-GigabitEthernet0/0/2]q然后开始配置（R1，R5）环回路由：
//R5
[R5]interface LoopBack 0
[R5-LoopBack0]ip address 192.168.9.0 24
Error: The specified IP address is invalid.
//这里有配置环路路由设置错误(设置成广播地址)
[R5-LoopBack0]ip address 192.168.9.1 24
//R1
[R1]interface LoopBack 0
[R1-LoopBack0]ip add
[R1-LoopBack0]ip address 192.168.1.1 24然后配置缺省路由：
//R4（R1的G0/0/1口）
[R4]ip route-static 0.0.0.0 0 4.0.0.2
//R5（R1的G0/0/2口）
[R5]ip route-static 0.0.0.0 0 1.0.0.2
//R6（R1的G0/0/0口）
[R6]ip route-static 0.0.0.0 0 2.0.0.2
在R1设置下一跳配置：
[R1]ip route-static 192.168.3.0 24 4.0.0.1
[R1]ip route-static 3.0.0.0 24 2.0.0.1
[R1]ip route-static 192.168.5.0 24 2.0.0.1
[R1]ip route-static 5.0.0.0 24 1.0.0.1
[R1]ip route-static 192.168.9.0 24 1.0.0.1
现在已经做到全网联通，开始设置客户端和服务端
