实验四路由器基本配置一、实验目的1、熟练掌握配置静态路由；2、学习使用路由总结。
二、实验内容1、拓扑结构图2、网络规划（2）IP3、进行路由器基本配置（1）路由器选择2621XM，为每台路由器安装模块WIC-2T，以便配置串行线路；（2）修改路由器名称。
4、配置环回端口为每个网络在相应的路由器上创建一个环回端口，并将端口地址设为该网络的网关地址。
（1）配置R1环回端口：R1>enR1r#conf tEnter configuration commands, one per line. End with CNTL/Z.R1(config)#interface loopback0%LINK-5-CHANGED: Interface Loopback0, changed state to up%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to upR1(config-if)#ip address 192.168.0.1 255.255.255.128R1(config-if)#exitR1(config)#interface loopback1%LINK-5-CHANGED: Interface Loopback1, changed state to upR1(config-if)#%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback1, changed state to up R1(config-if)#ip address 192.168.0.129 255.255.255.128R1(config-if)#exitR1(config)#interface loopback2%LINK-5-CHANGED: Interface Loopback2, changed state to up%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback2, changed state to up R1(config-if)#ip address 192.168.4.1 255.255.255.0（2）配置R2环回口：R2>enR2#conf tEnter configuration commands, one per line. End with CNTL/Z.R2(config)#interface loopback0%LINK-5-CHANGED: Interface Loopback0, changed state to up%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to up R2(config-if)#ip address 192.168.2.1 255.255.255.0（3）配置R3环回口：R3>enR3#conf tEnter configuration commands, one per line. End with CNTL/Z.R3(config)#interface loopback0%LINK-5-CHANGED: Interface Loopback0, changed state to up%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to up R3(config-if)#ip address 192.168.3.1 255.255.255.0（4）配置R4环回口：R4>enRouter#conf tEnter configuration commands, one per line. End with CNTL/Z.R4(config)#interface loopback0%LINK-5-CHANGED: Interface Loopback0, changed state to up%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to upR4(config-if)#ip address 192.168.5.1 255.255.255.192R4(config-if)#interface loopback1%LINK-5-CHANGED: Interface Loopback1, changed state to upR4(config-if)#%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback1, changed state to up R4(config-if)#ip address 192.168.5.65 255.255.255.192R4(config-if)#interface loopback2%LINK-5-CHANGED: Interface Loopback2, changed state to up%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback2, changed state to up R4(config-if)#ip address 192.168.5.129 255.255.255.1925、进行网络连通测试在4个路由器上使用ping命令分别测试每个网络的连通情况。
附R1运行ping测试效果：R1#ping 192.168.0.1Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 192.168.0.1, timeout is 2 seconds:!!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 0/1/3 msR1#ping 192.168.0.129Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 192.168.0.129, timeout is 2 seconds: !!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/3 msR1#ping 192.168.4.1Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 192.168.4.1, timeout is 2 seconds: !!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 1/3/5 msR1r#ping 192.168.2.1Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 192.168.2.1, timeout is 2 seconds: .....Success rate is 0 percent (0/5)R1#ping 192.168.3.1Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 192.168.3.1, timeout is 2 seconds: .....Success rate is 0 percent (0/5)R1#ping 192.168.5.1Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 192.168.5.1, timeout is 2 seconds: .....Success rate is 0 percent (0/5)R1#ping 192.168.5.65Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 192.168.5.65, timeout is 2 seconds: .....Success rate is 0 percent (0/5)R1#ping 192.168.5.129Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 192.168.5.129, timeout is 2 seconds: .....Success rate is 0 percent (0/5)6、配置路由器端口为4个路由器的串行端口配置IP地址，注意要在DCE设备上配置时钟，时钟波特率为64000。
然后打开端口。
7、配置静态路由（1）在R1上配置静态路由。
R1(config)#ip route 192.168.2.0 255.255.255.0 S0/0R1(config)#ip route 192.168.3.0 255.255.255.0 S0/0R1(config)#ip route 192.168.5.0 255.255.255.192 S0/0R1(config)#ip route 192.168.5.64 255.255.255.192 S0/0R1(config)#ip route 192.168.5.128 255.255.255.192 S0/0R1(config)#ip route 192.168.16.4 255.255.255.252 S0/0R1(config)#ip route 192.168.16.8 255.255.255.252 S0/0（2）在R2上配置静态路由。
R2(config)#ip route 192.168.0.0 255.255.255.128 S0/0R2(config)#ip route 192.168.0.128 255.255.255.128 S0/0R2(config)#ip route 192.168.4.0 255.255.255.0 S0/0R2(config)#ip route 192.168.3.0 255.255.255.0 S0/1R2(config)#ip route 192.168.5.0 255.255.255.192 S0/1R2(config)#ip route 192.168.5.64 255.255.255.192 S0/1R2(config)#ip route 192.168.5.128 255.255.255.192 S0/1R2(config)#ip route 192.168.16.8 255.255.255.252 S0/1（3）在R3上配置静态路由。
