一、网络拓扑：
二、帧中继全链接-RIP默认配置
1、帧中继交换机配置：
2、配置路由器帧中继接口
AR1:

AR3:
<Huawei>sys
[Huawei]undo info en
[Huawei]user con 0
[Huawei-ui-console0]idle 0 0
[Huawei-ui-console0]q
[Huawei]sys AR3
[AR1]int s1/0/0

[AR1-Serial1/0/0]int lo 0
[AR1-LoopBack0]ip add 192.1.3.1 24
3、路由配置（RIPv2协议）
AR1：
[AR1]rip
[AR1-rip-1]ver 2
[AR1-rip-1]net 123.0.0.0
[AR1-rip-1]net 192.1.1.0
AR2：
[AR2]rip
[AR2-rip-1]ver 2
[AR2-rip-1]net 123.0.0.0
[AR2-rip-1]net 192.1.2.0
AR3：
[AR3]rip
[AR3-rip-1]ver 2
[AR3-rip-1]net 123.0.0.0
[AR3-rip-1]net 192.1.3.0
4、验证配置：
在图中出现了多余的路由信息【红框】这是在华为的路由器串行接口启用【帧中继协议后，将接口的水平分割关闭了】
5、剔除多余路由【分别在三个路由器的S1/0/0接口-rip split-horizon 启用接口的rip水平分割】
