在eNSP里配置路由器与主机，IP地址与端口
配置PC2，特别注意IP地址与网关
配置路由器一
<Huawei>sys
[Huawei]int g0/0/0
[Huawei-GigabitEthernet0/0/0]ip add 192.168.1.254 24
[Huawei-GigabitEthernet0/0/0]int g0/0/1
[Huawei-GigabitEthernet0/0/1]ip add 192.168.2.1 24
分别配置两端IP地址，路由器会自动录入路由表
[Huawei-GigabitEthernet0/0/1]q
[Huawei]ip route-static 192.168.3.0 24 192.168.2.2
[Huawei]ip route-static 192.168.4.0 24 192.168.3.2
手动配置路由，先是邻居路由器二的第一个接口IP地址192.168.2.2与相关未知网段192.168.3.0/24
再依照顺序填入后续信息。

双击主机，测试，连同啦
练习二
再加一台主机
<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]ip route-static 192.168.5.0 24 192.168.2.2
<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]ip route-static 192.168.5.0 24 192.168.3.1
尝试ping，成功。
丢包的问题
例子：刚刚在测试连通性时，PC1与PC2的窗口显示的不同，第一次测试才出现超时。
