若ping自己IP则需要添加
R1:
R1(config)interface serial 1/0
R1(config-if)#frame-relay map ip 123.1.1.1 103 broadcast ietf
R2与R3同R1


添加环回口,启用RIP协议
loopback0:
R1:1.1.1.1/32
R2:2.2.2.2/32
R3:3.3.3.3/32
R1/2/3启用RIP:
router rip
version 2
no auto-summary
network x.x.x.x(宣告接口)
show ip route 查看路由条目,会有个个路由器的环回口的路由条目


开启水平分割,在中心节点开启
R1:
R1(config)#interface serial 1/0 ——(在中心节点路由开启水平分割)
R1(config-if)#ip split-horizon ——(接口开启)


R2和R3:clear ip route * 清空路由表
当水平分割开启时,启用子接口,
在之前的试验使用:default interface serial 1/0(清除接口的设置)
启用子接口时先关闭inverse-arp

开启后清理路由缓存
