RIP配置练习
本文主要是介绍RIP配置练习，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
要求分析：
1.R3自带环路，R1和R2需要配置两个环路，骨干链路自己设计 ，区域为192.168.1.0/24
2.使用RIPv2，且不能直接宣告R3环路
3.全网可达，数据安全（设置密文），汇总路由
解：
首先是网络地址的分析，需要2+1个网段2^n-2>3 --- n为3，借三位
192.168.1.0/24+3
192.168.1.0/27 ---骨干链路
192.168.1.0/30 --- R1和R2之间的地址段
192.168.1.4/30 ---R2和R3之间的地址段
192.168.1.32/27 ---R1环回
192.168.1.33/28 ---R1的环回1
192.168.1.49/28 ---R1的环回2
192.168.1.64/27 ---R2环回
192.168.1.65/28 ---R2的环回1
192.168.1.81/28 ---R2的环回2
此时地址已经分配完毕。
然后开始设置汇总:
R1 的汇总可以设置为192.168.1.32/27
R2 的汇总可以设置为192.168.1.64/27
这个时候不要忘记设置空接口，防止黑洞
然后就密文设置，我在R1和R2之间设置一个123456，R2和R3之间设置654321。
解题：

！！！为了安全起见，我在R1和R2之间设置密文登录，密文为123456
而R2和R3之间设置密文的密码为654321
