rip配置(上)

rip配置(上)：



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

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

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

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

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。
