要求：
R1-R2-R3-R4-R5 RIP 100运行版本2
R6-R7 RIP 200 运行版本1
1.使用合理IP地址规划网络，各自创建环回接口
2.R1创建环回 172.16.1.1/24 172.16.2.1/24 172.16.3.1/24
3.要求R3使用R2访问R1环回
4.减少路由条目数量，增加路由传递安全性
5.R5创建一个环回模拟运营商，不能通告
6.R1 telnet R2环回实际telnet 到R7上
7.R6-R7路由器不能学习到达R1环回路由
8.全网可达
分析：
1.配置IP地址
2.配置环回地址
3.启动RIP协议,使用version 1，进行RIP宣告，宣告的是主类地址
