实验时间：            机房：             组号：            机号：PC_B

一、    实验题目

      静态路由配置

二、    实验设备

      CISCO路由器，专用电缆，网线，CONSOLE线，PC机

三、    实验内容

n  了解路由的功能

n  在CISCO路由器上配置和验证静态路由

n  配置缺省路由

四、    原理

静态路由是指由网络管理员手工配置的路由信息。当网络的拓扑结构或链路的状态发生变化时，需要手工去修改路由表中相关的静态路由信息。静态路由信息在缺省情况下是私有的，不会传递给其他的路由器。静态路由一般适用于比较简单的网络环境，在这样的环境中，易于清楚地了解网络的拓扑结构，便于设置正确的路由信息。

五、    实际步骤

 1.设置PC_B的IP地址，连接路由器，打开超级终端。

     

2.路由器B的配置

Password:

5_R2#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

5_R2(config)#int s0/1/0

5_R2(config-if)#no shut

5_R2(config-if)#interface s0/1/0

5_R2(config-if)#ip addr

% Incomplete command.

3.配置routerB的s0/1/0端口的IP地址

5_R2(config-if)#ip address 172.17.200.6 255.255.255.252

5_R2(config-if)#^Z

4.配置路由器routerB的f0/1端口的IP地址

5_R2#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

5_R2(config)#int f0/1

5_R2(config-if)#ip address 10.5.2.1 255.255.255.0

5_R2(config-if)#^Z

5.配置路由器routerB的f0/0端口的IP地址

5_R2#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

5_R2(config)#int f0/0

5_R2(config-if)#ip addr 10.5.4.1 255.255.255.0

5_R2(config-if)#no shutdown

5_R2(config-if)#

6.PC_B能与PC2ping 通，不能ping PC１

7.在PC_B上配置缺省路由

5_R2(config)#ip route 10.5.1.0 255.255.255.0 172.17.200.5

5_R2(config)#exit

5_R2#show ip rout

5_R2#ping 10.5.1.123  （PCA）

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.5.1.123, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 12/14/16 ms
