5.3.1RIPV2的基本配置
Router rip
Ver 2
Network 网段
加油！
活着一日就当快乐一日
5.3.2与RIPV1的兼容性
打开关闭兼容性开关（就是排列组合）
你只能在R2上进行改动。
注意：实验的TOP、net文件、配置都在附件里面
1、R1 是RIPV1 R2的f0/1接口运行的是RIPV2，这边就可以改成RIPV1的接受和发送
2、R2f0/0去R4 R5，R4是V2 R5是V1，所以这边是即可以发送V1 也可以发送V2。（这边还用到了一个知识点就是关掉水平分隔。）可以相互说
步骤1
R2(config)#int f0/1
R2(config-if)#ip rip send ver 1
R2(config-if)#ip rip receive ver 1
R2(config-if)#end
Debug 可以看到RIPV1 和 RIPV2的区别
R2#debug ip rip
RIP protocol debugging is on

172.25.150.32/28但是没有转发出去。因为水平分隔
还有一个网段是直连的172.25.150.192/28这个段

这边就可以看到32和194这两个段被传送出去了
5.3.3使用VLSM
就是在化子网地址
