实验要求

1、R1和R5是客户A两个站点的CE设备，R6和R7是客户B两个站点的CE设备。设备MPLS VPN骨干网络分别连接不同客户的不同站点。

2、R1和R5采用静态路由的方式传递私网路由；R6通过RIP将私网路由传递给PE设备；R7通过OSPF将私网路由传递给PE设备。

3、R1与R2私网之间使用静态路由；R4与R5私网之间使用静态路由；R2与R6私网之间使用RIP；R4与R7私网之间使用OSPF。

3、R7单独拉一根网线保证可以访问公网，R7可以访问R2、R3、R4环回。

实验分析

实验需架设两个MPLS VPN，要注意区分VRF，指定RD和RT

在R2和R4上配置路由时必须分清公网和VRF

R7上配置缺省路由，使得R7能访问R2，R3，R4的环回
