4、BGP路由下一跳分析调试
分析10.9.0.0这条路由怎么在路由反射的过程如下：
首先复习一下路由反射器原则：
1.从客户端收到的路由反射给它的客户端和非客户端。
（RRC、IBGP和EBGP邻居）但是不向发送它的那个RRC公布；
2.从非客户端收到的路由只反射给它的客户端；
3.在进行路由反射之前，RR会进行路由选择，RR只把最优的路由反射出去；
4.RR进行路由反射时，不会改变路由的属性（包括下一跳、LP、MED等）来自EBGP邻居，则将它公布给所有邻居（IBGP、EBGP、RRC）；
5.有RR的情况下只有非客户端之间BGP路由不能互传；

5、BGP调试
分析的情况与拓扑图二一样的原理，此实验只是把路由反射嵌套了，其它的都一样。
实验总结
本次实验之中遇到了路由反射器问题。
在本次实验中，没有遇到什么大的困难，主要是配置太多，
实验不难，关键是要明白路由反射器反射原理及其原则。
