试验要求：
1 路由全通，要求R3、R2、R1看不到以上R4、R5的两个环回网络，其他所有路由器都可以看到全部的网络。
2 给R1设置5个环回接口，使用10.0.0.0/20的地址，运行RIPV2，配置单播更新，并要求发送路由更新时使用汇总后的地址。
3 在R2上运行RIPV2，并在R2与R3之间设置触发更新，使用MD5方式认证。
4 在R3与R5之间设置MD5认证。
5 在R3与R4之间设置MD5认证。
6 设置R4和R5两个环回网络之间的静态路由，并指定R3作为R4与R5的备份线路(浮动静态路由)。
7 开启OSPF的全区域认证，开启所有路由器的密码加密服务。
协议要求：
R3-R2-R1 RIPV2
R3-R4 OSPF
R3-R5 EIGRP
注意：所有牵扯到认证的地方，认证密码全部使用cisco
