静态路由能胜任多网段之间进行通信
有很多网友经常单机使用电脑，并不会接触路由器这个东西，所以会对这个东西不会了解，今天小编就来和大家说一下，下文是小编向您带来的静态路由也能胜任多网段之间进行通信，欢迎大家阅读。
如果多个网段之间要实现通信，必须使用路由器，这个毫无疑问。如果多个网段之间存在多个可选择的路径，最方便的是采取配置路由选择协议的方法，简单点的网络可以采用RIP协议，如果是复杂的网络则可以采用OSPF。当然在选择的路径不多时也可以采用静态路由的方法。
但是，当多个网段之间只有一条路径时，那么仅仅是配置静态路由就足够了。如果是在企业中工作，那么往往配置简单的静态路由就足够了。
为了更有说服力和便于理解我用CPT(Cisco Packet Tracer)演示了一下。
拓扑图如下图所示：
分别有四个网段，10.0.0.0/8、112.237.228.0/24、192.168.10.0/24、211.86.104.0/24。
静态路由设置如下：
ip route 192.168.10.0 255.255.255.0 112.237.228.1
ip route 211.86.104.0 255.255.255.0 112.237.228.1
ip route 10.0.0.0 255.0.0.0 112.237.228.244
ip route 211.86.104.0 255.255.255.0 192.168.10.1
ip route 112.237.228.0 255.255.255.0 192.168.10.2
ip route 10.0.0.0 255.0.0.0 192.168.10.2
配置如下：
1.PC0的IP配置：
Packet Tracer PC Command Line 1.0
PC>ipconfig
IP Address......................: 10.0.0.3
Subnet Mask.....................: 255.0.0.0
Default Gateway.................: 10.0.0.1
PC>
2.PC1的IP配置：
Packet Tracer PC Command Line 1.0
PC>ipconfig
IP Address......................: 211.86.104.52
Subnet Mask.....................: 255.255.255.0
Default Gateway.................: 211.86.104.254
PC>
3.R1的配置：
