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
R1在serial 1/0接口：
no frame-relay inverse-arp
no arp frame-relay
no shutdown
exit

R1(config)#default interface serial 1/0
Interface Serial1/0 set to default configuration

R1(config-if)#frame-relay lmi-type ansi
R1(config-if)#no shutdown
R1(config-if)#exit
R1(config)#interface serial 1/0.102 multipoint ——（R1到R2的子接口，启用多点连接）
R1(config-subif)#no frame-relay inverse-arp
R1(config-subif)#no arp frame-relay ——（子接口关闭inverse-arp可不敲，当主接口关闭子接口也会关闭）
R1(config-subif)#ip address 12.1.1.1 255.255.255.0
R1(config-subif)#frame-relay map ip 12.1.1.2 102 broadcast （做手工映射，）
R1(config-subif)#no shutdown
R1(config-subif)#exit
R1(config)#interface serial 1/0.103 point-to-point （R1到R3的子接口，点到点）

R1(config-subif)#no arp frame-relay
R1(config-subif)#ip address 13.1.1.1 255.255.255.0 （点到点不需要做帧中继映射，但需要做dlci绑定）
R1(config-subif)#frame-relay interface-dlci 103 （将这个子接口与103绑定，只要子接口发包就会标记该数据包，让FRSW知道怎么转发）

华为帧中继试验：

帧中继交换机配置：

帧中继交换机不需要配置，只需要配置R1R2R3
AR1:
   interface serial 1/0/0
   link-protocol fr（改为帧中继）
   Y
   fr interface type dte（默认都是DTE端）
   ip address 123.1.1.1 24
AR2:

   Y
   ip address 123.1.1.2 24
AR3:
   interface serial 1/0/0
   link-protocol fr
   Y
   ip address 123.1.1.3 24
AR1:
   display fr pvc-info
   display fr map-info（查看）
若AR2ping通AR3，AR2到AR3的手工映射

   fr map ip 123.1.1.3 201 broadcast
AR3：
   interface serial 1/0/0
   fr map ip 123.1.1.2 301 broadcast
display fr map-info（查看）

水平分割默认关闭，开启水平分割：
AR1:
   interface serial 1/0/0
   rip split-horizon
   rip poison-reverse
开启后清理路由缓存

<AR1>Reset ip routing-table statistics protocol rip
（bug：ensp中有可能一个有路由，一个没有，但是能得到结果不能ping通）
开启水平分割后启用子接口（重启所有路由器清空配置进行试验，也可以undo掉配置）
AR1：
   interface loopback 0
   ip address 1.1.1.1 24
   interface serial 1/0/0
   link-protocol fr
   undo fr inarp（关闭自动映射）
   quit
