Question

教你配置简单的静态路由

Answer 1

　　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：

　　Router>enable Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#hostname R1 R1(config)#interface FastEthernet0/1 R1(config-if)#ip address 10.0.0.1 255.0.0.0 R1(config-if)#no shutdown %LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up R1(config-if)#end R1# %SYS-5-CONFIG_I: Configured from console by console R1#conf t Enter configuration commands, one per line. End with CNTL/Z. R1(config)#int f0/0 R1(config-if)#ip addr 112.237.228.244 255.255.255.0 R1(config-if)#no shutdown %LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up R1(config-if)#end R1# %SYS-5-CONFIG_I: Configured from console by console R1#conf t Enter configuration commands, one per line. End with CNTL/Z. R1(config)#ip route 192.168.10.0 255.255.255.0 112.237.228.1 R1(config)#ip route 211.86.104.0 255.255.255.0 112.237.228.1 R1(config)#end R1# %SYS-5-CONFIG_I: Configured from console by console R1#

　　4.R2的配置：

　　Router>enable Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#hostname R2 R2(config)# R2(config)#interface FastEthernet0/1 R2(config-if)#ip address 112.237.228.1 255.255.255.0 R2(config-if)#no shutdown %LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up R2(config-if)# R2(config-if)#exit R2(config)#interface FastEthernet0/0 R2(config-if)#ip address 192.168.10.2 255.255.255.0 R2(config-if)#no shutdown %LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up R2(config-if)#end R2#conf t Enter configuration commands, one per line. End with CNTL/Z. R2(config)#ip route 10.0.0.0 255.0.0.0 112.237.228.244 R2(config)#ip route 211.86.104.0 255.255.255.0 192.168.10.1 R2(config)#end R2# %SYS-5-CONFIG_I: Configured from console by console R2#

　　5.R3的配置：

　　Router>enable Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#hostname R3 R3(config)# R3(config)#interface FastEthernet0/1 R3(config-if)#ip address 192.168.10.1 255.255.255.0 R3(config-if)#no shutdown %LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up R3(config-if)# R3(config-if)#exit R3(config)#interface FastEthernet0/0 R3(config-if)#ip address 211.86.104.254 255.255.255.0 R3(config-if)#no shutdown R3(config-if)# %LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up R3>enable R3#conf t Enter configuration commands, one per line. End with CNTL/Z. R3(config)#ip route 112.237.228.0 255.255.255.0 192.168.10.2 R3(config)#ip route 10.0.0.0 255.0.0.0 192.168.10.2 R3(config)#end R3# %SYS-5-CONFIG_I: Configured from console by console R3#

　　6.使用tracert进行测试：

　　测试从PC0能否路由到PC1。

　　结果表明测试成功。

　　测试从PC1能否路由到PC0。

　　结果表明测试成功。
