cisco路由器模拟帧中继交换机

注：实验拓扑图和配置步骤参照 http://wry000.blog.51cto.com/821590/272088，感谢wry的分享。

拓扑图：

1.把路由器R4配置为帧中继交换机

  

frame-relay  switching   *配置为帧中继交换机

2.在路由器R4上配置接口的时钟频率、封装类型、lmi类型和帧中继dce端

  

int s0/0

no shut

clock rate 64000   *设置时钟频率

encapsulation frame-relay    *封装为帧中继

frame-relay lmi-type cisco   *lmi类型为cisco

frame-relay intf-type dce    *帧中继的dce端

int s0/1

no shut

clock rate 64000

encapsulation frame-relay

frame-relay lmi-type cisco

frame-relay intf-type dce

int s0/2

no shut

clock rate 64000

encapsulation frame-relay

frame-relay lmi-type cisco

frame-relay intf-type dce

exit

3.在路由器R4接口上配置帧中继交换表

int s0/0

frame-relay route 102 interface Serial0/1 201

frame-relay route 104 interface Serial0/2 401

int s0/1

frame-relay route 201 interface Serial0/0 102

frame-relay route 301 interface Serial0/2 103

int s0/2

frame-relay route 401 interface Serial0/0 104

frame-relay route 103 interface Serial0/1 301

4.在R1、R2、R3路由器上配置接口IP，并封装为帧中继

  R2:

  R3:

 encapsulation frame-relay

 frame-relay lmi-type cisco

5.验证配置结果
