标签：1.1 RR default 0.0 BGP peer interface 2.2 组网

1、实验拓扑图

三十三、配置 BGP 备份 RR 实验组网_Standard

2、实验目的

配置R1、R2、R3和R4配置集群，R1与R2相互备份，配置相同的“reflector cluster-id 1.1.1.1”，观察结果

3、实验具体配置

4、实验现象

三十三、配置 BGP 备份 RR 实验组网_Standard_02

三十三、配置 BGP 备份 RR 实验组网_ci_03

5、知识总结

1）client只与RR建立对等体

2）RR1与RR2需要统一使用一个cluster-id

3）注意区分发送与反射的区别

4）RR1与RR2不分主备
