经典企业网内部OSPF路由选路

实验：
为了增加网络带宽以及网络流量的监控 ，本公司设置了俩台专门负责办公和业务的路由器。
要求：
1、全网可达
2、分部办公网络只能走办公路由器，分部业务网络智能走分部路由器。
3、路由器之间采取OSPF的方式进行联通

配置思路：首先我们想，流量要分开走，必须要上策略，前缀列表必须在重发布上完成，所以我们需要俩个进程。在办公路由器和业务路由器上进行重分布的配置。

配置：

配置完成我们测试 先看R5 R6 R7 的路由表：



下一跳都没有问题我们在追踪一下流量
在R5上：

R6:

R7：

注：如果分部之间不相互通信的话 我们再起一个进程 来完成！
