静态路由是指用户或网络管理员手工配置的路由信息。当网络的拓扑结构或链路状态发生改变时，需要网络管理人员手工修改静态路由信息。相比于动态路由协议，静态路由无需频繁地交换各自的路由表，配置简单。比较适合小型，简单的网络环境。

首先配置IP
端口配置IP地址部分略 命令=ip add “ip地址” “子网掩码”
IP 地址的主机位为其设备编号如R1 S0/0/0 端口在192.168.12.0网段，则该端口IP为192.168.12.1.以此类推.
这里我将R2的 E 0/0/0 口配置为192.168.20.2 /24.故PC2的网关地址为192.168.20.3/24.
这里将R1的 E 0/0/0 口配置为192.168.10.1/24.故PC1的网关地址为192.168.10.1/24.
实验步骤
[R1][R1]ip route-static 192.168.20.0 24 10.0.12.2
在R1上配置目的网段为PC-2所在网段的静态路由，地址为
192.168.20.0 子网掩码为255.255.255.0，数据发送到PC-2
需要先发送给R2，所以R2为R1的下一跳路由器，之间的直连链路
上的物理接口的IP地址即为下一跳IP地址，为10.0.12.2.

**这里用PC-1pingPC-2 发现无法建立连接，因为现在的配置
只是PC-1能够发送给PC-2数据，但是PC-2无法传送给PC-1.**
[R3]ip route-static 192.168.10.0 24 10.0.23.2
