TCP/IP 5.3RIPV2的基本配置
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

：
在没有关掉水平分隔时候的情况

R2(config-if)#ip rip send ver 1 2

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
步骤
3
：水平分隔的关闭
R2(config)#int f0/0
