CCNA之四：RIPV1和EIGRP在不连续网络下的比较

 环境：两台2500系列路由器，由串口相连。

要求：在RIPv1和EIGRP中将两个相同主类网络的不同子网由另一个主类网络分割，如何能学到对端网络。

 

 

RIP配置：

 

步骤一、基本配置

 

Router>

Router>enable

Router#config terminal

Router(config)#hostname R1

R1(config)#no ip domain-lookup 

R1(config)#line console 0

R1(config-line)#logging synchronous     

R1(config-line)#exec-timeout 0 0 

R1(config-line)#exit

 

步骤二、接口配置

 

R1的配置：

R1(config)#interface s0

R1(config-if)#ip address 172.16.1.1 255.255.255.0

R1(config-if)#clock rate 64000    

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：

R2(config)#interface s1

R2(config-if)#ip add 172.16.1.2 255.255.255.0

R2(config-if)#no shutdown

R2(config-if)#interface loopback 0

R2(config-if)#ip address 10.1.2.1 255.255.255.0

R2(config-if)#exit

R2(config)#

 

步骤三、启用RIP路由选择协议

R1(config-router)#exit

R1(config)#

 

R2的配置：

R2(config)#router rip              à启用RIP

R2(config-router)#network 10.0.0.0  à发布直连网段

R2(config-router)#network 172.16.0.0

R2(config-router)#exit

R2(config)#end

     10.0.0.0/24 is subnetted, 4 subnets

C       10.1.3.0 is directly connected, Serial0

R       10.1.2.0 [120/1] via 10.1.3.2, 00:00:14, Serial0   à已经学习到了路由

R       10.0.0.0 [120/1] via 172.16.1.2, 00:00:14, Serial0
