路由器的作用是：打通不同网络（局域网）的网络。

直连路由设置

路由表

[Huawei]dis ip routint-table 192.168.2.2
[Huawei]
[Huawei]ip route-static 192.168.2.0 255.255.255.0 10.1.1.2
                        //目的地                   //下一跳  
[Huawei]dis ip routint-table 192.168.2.2
[Huawei] 此时能够查到信息

但是现在还是ping不通，需要做一套回程的信息
此时就可以ping通过了

关于路由表

第一个交换机的配置

<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]int g0/0/0
[Huawei-GigabitEthernet0/0/0]ip add 192.168.1.254 255.255.255.0

[Huawei-GigabitEthernet0/0/0]int g0/0/1
[Huawei-GigabitEthernet0/0/1]ip add 10.1.1.1 255.255.255.0

[Huawei-GigabitEthernet0/0/1]int g0/0/2
[Huawei-GigabitEthernet0/0/2]ip add 10.2.2.1 255.255.255.0

[Huawei-GigabitEthernet0/0/2]quit

[Huawei]dis ip routing-table 192.168.2.2
[Huawei]
[Huawei]ip route-static 192.168.2.0 255.255.255.0 10.1.1.2

[Huawei]dis ip routing-table 192.168.2.2

第二个交换机的配置

<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]int g0/0/0
[Huawei-GigabitEthernet0/0/0]ip add 10.1.1.1 255.255.255.0


[Huawei-GigabitEthernet0/0/0]int g0/0/1
[Huawei-GigabitEthernet0/0/1]ip add 192.168.2.254 255.255.255.0

[Huawei]ip route-static 192.168.1.1 255.255.255.0 10.1.1.1

[Huawei-GigabitEthernet0/0/1]dis ip routing-table 192.168.1.1
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------

在第一台和第二台电脑上配置网关，补齐子网掩码，即可ping通

PC>ping 192.168.2.2

取消第二个交换机的路由


[Huawei]undo ip route-static 192.168.1.1 255.255.255.0 10.1.1.1
Warning: The destination address and the mask do not match, and thus the static 
route 192.168.1.0/24 will be deleted. Continue?[Y/N]:Y

也能ｐｉｎｇ通
