实验11RIPv1 基本配置
1.实验目的
通过本实验可以掌握:
1)在路由器上启动RIPv1 路由进程
2)启用参与路由协议的接口,并且通告网络
3)理解路由表的含义
4)查看和调试RIPv1 路由协议相关信息
2.拓扑结构
实验拓扑如图 所示。
3.实验步骤
 
1)步骤1:配置路由器R0
Router>en
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#ho r0
r0(config)#no ip domain-loo
r0(config)#lin c 0
r0(config-line)#logg s
r0(config-line)#exit
r0(config)#lin c 0
r0(config-line)#exec-t 00
r0(config-line)#exit
r0(config)#int s1/1/0
r0(config-if)#ip add 192.168.12.1 255.255.255.0
r0(config-if)#no sh
 
%LINK-5-CHANGED: Interface Serial1/1/0, changed state to down
r0(config-if)#exit
r0(config)#int loo 1
 
%LINK-5-CHANGED: Interface Loopback1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback1, changed state to up
r0(config-if)#ip add 1.1.1.1 255.255.255.0
%LINK-5-CHANGED: Interface Serial1/1/0, changed state to up
r0(config-if)#^Z
%SYS-5-CONFIG_I: Configured from console by console
r0#sh ip int b
Interface              IP-Address      OK? Method Status                Protocol
 
FastEthernet0/0        unassigned      YES manual administratively down down
 
FastEthernet0/1        unassigned      YES manual administratively down down
 
FastEthernet1/0        unassigned      YES manual administratively down down

Vlan1                  unassigned      YES manual administratively down down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/1/0, changed state to up
r0#sh ip int b
Interface              IP-Address      OK? Method Status                Protocol
 
FastEthernet0/0        unassigned      YES manual administratively down down
 
FastEthernet0/1        unassigned      YES manual administratively down down
 
FastEthernet1/0        unassigned      YES manual administratively down down
 
Serial1/1/0            192.168.12.1    YES manual up                    up
 
Serial1/1/1            unassigned      YES manual administratively down down
 
Loopback1              1.1.1.1         YES manual up                    up
 
Vlan1                  unassigned      YES manual administratively down down
r0#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
r0(config)#router rip
//启动RIP 进程
r0(config-router)#ver 1//配置RIP 版本1
r0(config-router)#net 1.1.1.0//通告网络
r0(config-router)#net 192.168.12.0
r0(config-router)#do ping 192.168.34.2
 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.34.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 93/93/94 ms
 
r0(config-router)#do ping 4.4.4.4
 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 4.4.4.4, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 78/90/94 ms
 
r0(config-router)#do sh ip route //该命令用来查看路由表。
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
       * - candidate default, U - per-user static route, o - ODR
       P - periodic downloaded static route
 
Gateway of last resort is not set
 
     1.0.0.0/24 is subnetted, 1 subnets
C       1.1.1.0 is directly connected, Loopback1
R    4.0.0.0/8 [120/3] via 192.168.12.2, 00:00:26, Serial1/1/0
C    192.168.12.0/24 is directly connected, Serial1/1/0
R    192.168.23.0/24 [120/1] via 192.168.12.2, 00:00:26, Serial1/1/0
R    192.168.34.0/24 [120/2] via 192.168.12.2, 00:00:26, Serial1/1/0
以上输出表明路由器R1 学到了3 RIP 路由,其中路由条目“R 4.0.0.0/8 [120/3]
via 192.168.12.2, 00:00:26, Serial1/1/0”的含义如下:
R:路由条目是通过RIP 路由协议学习来的;
4.0.0.0/8:目的网络;
120RIP 路由协议的默认管理距离;
3: 度量值,从路由器R1 到达网络4.0.0.0/8 的度量值为3 跳;
192.168.12.2:下一跳地址;
00:00:26:距离下一次更新还有430-26)秒;
Serial1/1/0:接收该路由条目的本路由器的接口。
同时通过该路由条目的掩码长度可以看到,RIPv1 确实不传递子网信息。
