实验需求

1、让 R3 可以学到R1的 192.168.10.0/24和192.168.20.0/24的 路由，不能学到192.168.30.0/24。
2、让 R1可以学到 R3 的 172.16.20.0/24和172.16.30.0/24的路由，不能学到 172.16.10.0/24，并且cost 设置为 10。

检验

AR1身上已经学到了AR3的两条路由，并且跳数设置为11
AR1到AR2需要1跳，AR1又从AR2身上学到了AR3的两条路由，跳数又为10
所以总得跳数就为11啦，说明实验效果成功啦

此时AR3已经学到了AR1的192.168.10.0/24和192.168.20.0/24
