靜態(tài)路由能勝任多網(wǎng)段之間進(jìn)行通信
有很多網(wǎng)友經(jīng)常單機(jī)使用電腦，并不會接觸路由器這個東西，所以會對這個東西不會了解，今天小編就來和大家說一下，下文是小編向您帶來的靜態(tài)路由也能勝任多網(wǎng)段之間進(jìn)行通信，歡迎大家閱讀。
如果多個網(wǎng)段之間要實現(xiàn)通信，必須使用路由器，這個毫無疑問。如果多個網(wǎng)段之間存在多個可選擇的路徑，最方便的是采取配置路由選擇協(xié)議的方法，簡單點的網(wǎng)絡(luò)可以采用RIP協(xié)議，如果是復(fù)雜的網(wǎng)絡(luò)則可以采用OSPF。當(dāng)然在選擇的路徑不多時也可以采用靜態(tài)路由的方法。
但是，當(dāng)多個網(wǎng)段之間只有一條路徑時，那么僅僅是配置靜態(tài)路由就足夠了。如果是在企業(yè)中工作，那么往往配置簡單的靜態(tài)路由就足夠了。
為了更有說服力和便于理解我用CPT(Cisco Packet Tracer)演示了一下。
拓?fù)鋱D如下圖所示：
分別有四個網(wǎng)段，10.0.0.0/8、112.237.228.0/24、192.168.10.0/24、211.86.104.0/24。
靜態(tài)路由設(shè)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：
