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。
实验思路
1、首先配置骨干链路的IP地址及环回接口，启动IGP协议OSPF和激活MPLS通道。
2、配置客户站点的IP地址及环回接口，并划分不同通道，配置相关的路由协议。
3、中间骨干链路启动MP-BGP协议使得路由信息可以传递。
4、在R7上配置缺省路由，使得R7可以访问R2、R3、R4环回。
