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:

6.使用tracert进行测试:
测试从PC0能否路由到PC1。
