实验5 全区域中通过桢中继实现RIPv2路由协议 + 密钥验证

　　为什么非要加入密钥验证部分，因为现实中它基本上是必须的

　　[P1&P2&BBR]通用部分

router rip
ver 2
net x.x.x.x
key chain cisco
key 1
key-string mypass
int x/x.x
ip rip auth key cisco
ip rip auth mod md5
[P1R1]
int s1/0
ip add 10.0.0.2 255.0.0.0
no shut
ip rip auth key cisco
ip rip auth mod md5
encpa fr
fr map ip 10.0.0.1 103 br

　　[P1R2　P2R1　P2R2]配置都是这样，不再阐述

[BBR1]
int s1/0
no ip add
no shut
int s1/0.1 mu
ip add 10.0.0.1
fr map ip 10.0.0.2 301 br
fr map ip 10.0.0.3 302 br
ip rip auth key cisco
ip rip auth mod md5
[BBR2]
int s1/0
no ip add
no shut
int s1/0.1 mu
ip add 11.0.0.1
fr map ip 11.0.0.2 604 br
fr map ip 11.0.0.3 605 br
ip rip auth key cisco
ip rip auth mod md5

　　验证结果：
