帧中继交换机的配置

配置步骤如下:
1.启用帧中继交换机功能
router(config)#frame-relay switching
2.在接口模式下封装
router(config-if)#encapsulation  frame-relay
3.指定Lmi-type (cisco ansi q933a)
router(config-if)#frame-relay lmi-type cisco
4.指定intf-type (dce dte nni)
router(config-if)#frame-relay intf-type dce
5.配置时钟:

router(config-if)#clock rate 56000

6.配置DLCI
s0/2接口下:
router(config-if)#frame-relay route 502 interface serial 0/0 205
router(config-if)#frame-relay route 501 interface serial 0/1 105
s0/0接口下:
router(config-if)#frame-relay route 205 interface serial 0/2 502

router(config-if)#frame-relay route 205 interface serial 0/2 105

s0/1接口下:
router(config-if)#frame-relay route 105 interface serial 0/2 501

router(config-if)#frame-relay route 105 interface serial 0/2 205

6.查看配置:
router#show frame-relay route
