cisco路由器基本实验之二 默认路由的配置(Boson NetSim)

  昨天做的是静态路由的配置,按照Boson NetSim上面写的实验计划,后面还有一系列的实验,如下图所示: 昨天做的就是Laber4 静态路由的配置,今天则是Laber5,默认路由的配置,还是和昨天一样,我把关键语句的意思即理解写在了这些语句的后面,下面是我的配置情况:
   拓扑图还是昨天那幅图:
具体配置如下:
r1的配置:
 
Press Enter to Start

Router>
Router>en
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#hostname router1
router1(config)#interface e0
router1(config-if)#ip address 192.168.1.2 255.255.255.0
router1(config-if)#no shut
%LINK-3-UPDOWN: Interface Ethernet0, changed state to up
router1(config-if)#interface s0
router1(config-if)#ip address 192.168.2.1 255.255.255.0

router1(config)#ip route 0.0.0.0 0.0.0.0 192.168.2.1
router1(config)#ip classless
                    ^
% Invalid input detected at '^' marker.            //可能是路由器型号太低或者是模拟软件的bug,ip classless无效
router1(config-if)#exit
router1(config)#exit
router1#copy running startup
Destination filename [startup-config]?
Building configuration...
[OK]
%LINK-3-UPDOWN: Interface Serial0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0, changed state to up
 
r2 的配置:
 
Press Enter to Start

Router>en
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface s0
Router(config-if)#ip address 192.168.2.2 255.255.255.0
Router(config-if)#no shut
%LINK-3-UPDOWN: Interface Serial0, changed state to up

Router(config-if)#ip address 192.168.3.1 255.255.255.0
Router(config-if)#no shut
%LINK-3-UPDOWN: Interface Ethernet0, changed state to up
Router(config-if)#exit
Router(config)#ip route 0.0.0.0 0.0.0.0 192.168.2.2
Router(config)#exit
Router#copy running startup
Destination filename [startup-config]?
Building configuration...
[OK]
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#hostname router2                   //不好意思,刚开始忘了设主机名了
router2(config)#exit
router2#ping 192.168.1.2                          //先试ping下路由,显示成功
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

  默认路由的配置就到此成功了,总结一下,关键语句是:
ip route 0.0.0.0 0.0.0.0 下一跳IP地址,希望大家都能实验成功!
