实验目的：
        (1)简单rip配置
        (2)rip v1与rip v2兼容问题

 

 

 

(1)简单rip配置：

r1配置：

基本信息配置：
Router>en
Router#conf t
Router(config)#enable secret abc
Router(config)#line console 0
Router(config-line)#password abc
Router(config-line)#login
Router(config-line)#logging synchronous
Router(config-line)#exec-timeout 0 0
Router(config-line)#exi
Router(config)#no ip domain lookup
Router(config)#hostname r1

接口信息配置：
r1(config)#in s1/0
r1(config-if)#ip add 219.146.0.1 255.255.255.0
r1(config-if)#no shut
r1(config-if)#in s1/1
r1(config-if)#ip add 219.146.2.1 255.255.255.0
r1(config-if)#no shut
r1(config-if)#exi

rip v2配置：
r1(config)#router rip
r1(config-router)#version 2             //rip版本2
r1(config-router)#no auto-summary       //不自动汇总
r1(config-router)#network 219.146.0.0   //添加直连网络
r1(config-router)#network 219.146.2.0
r1(config-router)#exi

 

r2配置：

基本信息配置
Router>en
Router#conf t
Router(config)#enable secret abc
Router(config)#line console 0
Router(config-line)#password abc
Router(config-line)#login
Router(config-line)#logging synchronous
Router(config-line)#exec-timeout 0 0
Router(config-line)#exi
Router(config)#no ip domain lookup
Router(config)#hostname r2

接口信息配置：
r2(config)#in s1/0
r2(config-if)#ip add 219.146.0.2 255.255.255.0
r2(config-if)#no shut
r2(config-if)#in s1/2
r2(config-if)#ip add 219.146.1.1 255.255.255.0
r2(config-if)#no shut
r2(config-if)#exi

rip v2配置：
r2(config)#router rip
r2(config-router)#version 2
r2(config-router)#no auto-summary
r2(config-router)#network 219.146.0.0
r2(config-router)#network 219.146.1.0
r2(config-router)#exi

 

r3配置：

基本信息配置：
Router>en
Router#conf t
Router(config)#enable secret abc
Router(config)#line console 0
Router(config-line)#password abc
Router(config-line)#login
Router(config-line)#logging synchronous
Router(config-line)#exec-timeout 0 0
Router(config-line)#exi
Router(config)#no ip domain lookup
Router(config)#hostname r3

接口信息配置：
r3(config)#in s1/2
r3(config-if)#ip add 219.146.1.2 255.255.255.0
r3(config-if)#no shut
r3(config-if)#in s1/1
r3(config-if)#ip add 219.146.2.2 255.255.255.0
r3(config-if)#no shut
r3(config-if)#exi

rip v2配置：
r3(config)#router rip
r3(config-router)#version 2
r3(config-router)#no auto-summary
r3(config-router)#network 219.146.1.0
r3(config-router)#network 219.146.2.0
r3(config-router)#exi

rip v2的一般配置就完成了，已经可以正常路由了，很简单吧!

 

(2)rip v1与rip v2兼容问题

r2(config)#router rip
r2(config-router)#no version 2    //让r2的rip版本为v1版
r2(config-router)#exi

 

结果如下：
r1(config)#do show ip route      //查看路由表
Codes: C - connected, S - static, 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
       i - IS-IS, su - IS-IS summary, 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

C    219.146.2.0/24 is directly connected, Serial1/1
C    219.146.0.0/24 is directly connected, Serial1/0
R    219.146.1.0/24 [120/1] via 219.146.2.2, 00:00:21, Serial1/1
                    [120/1] via 219.146.0.2, 00:00:19, Serial1/0

发现一切正常，没变化。

r1(config)#end
r1#clear ip route *       //重新学习一下路由表
r1#show ip route
Codes: C - connected, S - static, 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
       i - IS-IS, su - IS-IS summary, 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

C    219.146.2.0/24 is directly connected, Serial1/1
C    219.146.0.0/24 is directly connected, Serial1/0
R    219.146.1.0/24 [120/1] via 219.146.2.2, 00:00:09, Serial1/1

问题出来了，到219.146.1.0只有一条路由了。

 

同样，在r3上也查看如下：
r3(config)#do show ip route
Codes: C - connected, S - static, 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
       i - IS-IS, su - IS-IS summary, 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

C    219.146.2.0/24 is directly connected, Serial1/1
R    219.146.0.0/24 [120/1] via 219.146.2.1, 00:00:18, Serial1/1
                    [120/1] via 219.146.1.1, 00:00:44, Serial1/2
C    219.146.1.0/24 is directly connected, Serial1/2
r3(config)#end
r3#clear ip route *      //重新学习路由表
r3#show ip route
Codes: C - connected, S - static, 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
       i - IS-IS, su - IS-IS summary, 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

C    219.146.2.0/24 is directly connected, Serial1/1
R    219.146.0.0/24 [120/1] via 219.146.2.1, 00:00:07, Serial1/1
C    219.146.1.0/24 is directly connected, Serial1/2

 

问题同上，但此时r2的路由表却没有改变，因此，得出结论：

v1能学到v2的路由表，但v2不能学到v1的。

 

有两种解决方法：

 

 

 

一、在rip v1上操作：
r2(config)#in s1/0                      //进接口
r2(config-if)#ip rip send version 2     //发送v2版的更新包
r2(config-if)#exi

结果如下：
r1#clear ip route *
r1#show ip route
Codes: C - connected, S - static, 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
       i - IS-IS, su - IS-IS summary, 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

C    219.146.2.0/24 is directly connected, Serial1/1
C    219.146.0.0/24 is directly connected, Serial1/0
R    219.146.1.0/24 [120/1] via 219.146.2.2, 00:00:07, Serial1/1
                    [120/1] via 219.146.0.2, 00:00:03, Serial1/0

发现已经正常了，说明已经解决问题。

 

 

二、在rip v2上操作：
r3#conf t
r3(config)#in s1/2                         //进接口
r3(config-if)#ip rip receive version 1     //接收v1版的更新包
r3(config-if)#exi
r3(config)#do show ip route
Codes: C - connected, S - static, 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
       i - IS-IS, su - IS-IS summary, 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

C    219.146.2.0/24 is directly connected, Serial1/1
R    219.146.0.0/24 [120/1] via 219.146.2.1, 00:00:24, Serial1/1
                    [120/1] via 219.146.1.1, 00:00:15, Serial1/2
C    219.146.1.0/24 is directly connected, Serial1/2

发现也已经正常，说明办法可行。

 

实验完成。
