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

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
