CCNA之三：RIP协议

环境：两台2500系列路由器由串口相连。

   要求：如下图所示，在R1和R2上运行RIPv1,让两端能够学习到对端的路由以达到通信的目的。   

 

 

步骤一、基本配置

 

Router>

Router>enable

Router#config terminal

Router(config)#hostname R1

R1(config)#no ip domain-lookup   à关闭域名查找

R1(config)#line console 0

R1(config-line)# logging synchronous à命令输入达到同步

R1(config-line)#exec-timeout 0 0   à设置永不超时

R1(config-line)#exit

 

步骤二、接口IP配置

 

R1的配置：

R1(config)#interface s0

R1(config-if)#ip address 30.1.1.1 255.255.255.0

R1(config-if)#clock rate 64000     à注意时钟速率端

R1(config-if)#no shutdown

R1(config-if)#interface loopback 0

R1(config-if)#ip address 10.1.1.1 255.255.255.0

R1(config-if)#

 

R2的配置：

Router(config)#hostname R2

R2(config)#interface s1

R2(config-if)#ip address 30.1.1.2 255.255.255.0

R2(config-if)#no shutdown

R2(config-if)#interface loopback 0

R2(config-if)#ip address 20.1.1.1 255.255.255.0

R2(config-if)#exit

R2(config)#

 

步骤三、启用RIP路由选择协议

 

R1的配置：

R1(config)#router rip         à启用RIP

R1(config-router)#network 30.0.0.0  à发布直连网段

R1(config-router)#network 10.0.0.0

R1(config-router)#exit

R1(config)#

 

R2的配置：

R2(config)#router rip        à启用RIP

R2(config-router)#network 20.0.0.0  à发布直连网段

R2(config-router)#network 30.0.0.0

R2(config-router)#exit

R2(config)#end

 

 

步骤四、显示路由表，查看路由条目

 

R1#show ip route

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

 

R    20.0.0.0/8 [120/1] via 30.1.1.2, 00:00:03, Serial0    à学习来的路由条目

     10.0.0.0/24 is subnetted, 1 subnets

C       10.1.1.0 is directly connected, Loopback0

     30.0.0.0/24 is subnetted, 1 subnets

C       30.1.1.0 is directly connected, Serial0

 

 

步骤五、用扩展ping命令测试连通性

R2#ping

Protocol [ip]:

Target IP address: 10.1.1.1

Repeat count [5]:

Datagram size [100]:

Timeout in seconds [2]:

Extended commands [n]: y

Source address or interface: 20.1.1.1

!!!!!

 

步骤六、显示你当前路由协议

R2#show ip protocols          à显示你当前路由协议配置情况和运行状态

Routing Protocol is "rip"   

  Sending updates every 30 seconds, next due in 24 seconds

  Invalid after 180 seconds, hold down 180, flushed after 240

  Outgoing update filter list for all interfaces is

  Incoming update filter list for all interfaces is

  Redistributing: rip

  Default version control: send version 1, receive any version

    Interface             Send  Recv  Triggered RIP  Key-chain

    Loopback0             1     1 2

    Serial1                1     1 2

  Automatic network summarization is in effect

  Routing for Networks:

    10.0.0.0

    20.0.0.0

  Routing Information Sources:

    Gateway         Distance      Last Update

    30.1.1.1             120      00:14:05

  Distance: (default is 120)

 

 

步骤七、显示当前配置

 

r1的当前配置：

r1#show running-config

!

hostname R1

!

no ip domain-lookup

!

interface Loopback0

 ip address 10.1.1.1 255.255.255.0

!

interface Serial0

 ip address 30.1.1.1 255.255.255.0

 clockrate 64000

!

router rip

network 30.0.0.0

network 10.0.0.0

!

line con 0

 exec-timeout 0 0

 logging synchronous

 transport input none

end

 

r2的当前配置：

R2#sh run

!

hostname R2

!

no ip domain-lookup

!

interface Loopback0

 ip address 20.1.1.1 255.255.255.0

!

interface Serial1

 ip address 30.1.1.2 255.255.255.0

!

router rip

network 30.0.0.0

network 20.0.0.0

!

line con 0

 exec-timeout 0 0

 logging synchronous

!

end

偶不总结了~知道v1和v2就好了~！
