配置思路:

1、先配置FR-SWITCH

2、再配置RTA、RTB、RTC

FR-SWITCH详细配置步骤如下:

[FR-Switch]fr switching  //启动路由器帧中继功能

[FR-Switch]interface s6/0

[FR-Switch-Serial6/0]link-protocol fr  //链路协议封闭为FR

[FR-Switch-Serial6/0]fr interface-type dce   //配置帧中继接口类型为DCE

[FR-Switch-Serial6/0]fr dlci 30  //配置RTB到RTA的DLCI为30

[FR-Switch-fr-dlci-Serial6/0-30]quit

[FR-Switch-Serial6/0]fr dlci 40  //配置RTC到RTA的DLCI为40

[FR-Switch-fr-dlci-Serial0/0/0-30]quit

 

[FR-Switch]interface s0/0/1

[FR-Switch-Serial0/0/1]link-protocol fr

[FR-Switch-Serial0/0/1]fr interface-type dce

[FR-Switch-Serial0/0/1]fr dlci 70

[FR-Switch-fr-dlci-Serial0/0/1-70]quit

 

[FR-Switch]interface s0/0/2

[FR-Switch-Serial0/0/2]fr interface-type dce

[FR-Switch-Serial0/0/2]fr dlci 80

[FR-Switch-fr-dlci-Serial0/0/2-80]quit

 

[FR-Switch]fr switch a-b interface s0/0/0 dlci 30 interface Serial 0/0/1 dlci 70

[FR-Switch-fr-switching-a-b]quit

[FR-Switch]fr switch a-c interface s0/0/0 dlci 40 interface s0/0/2 dlci 80

[FR-Switch-fr-switching-a-c]quit

 

RTA配置如下:

[RTA]interface s1/0

[RTA-Serial1/0]ip add 10.1.1.1 24

[RTA-Serial1/0]link-protocol fr

[RTA-Serial1/0]fr interface-type dte  //配置帧中继接口类型为DTE,H3C路由器默认是DTE,所以可以省去这步

[RTA-Serial1/0]fr lmi type q933a   //配置LMI类型为Q933a

 

[RTA-Serial1/0]fr map ip 10.1.1.2 30  //配置通信对方(即RTB)的IP地址与本地DLCI号的映射

[RTA-Serial1/0]fr map ip 10.1.1.3 40  配置通信对方(即RTC)的IP地址与本地DLCI号的映射

 

RTB的配置如下:

 

[RTB]interface s0/0

[RTB-Serial0/0]ip add 10.1.1.2 24

[RTB-Serial0/0]link-protocol fr

[RTB-Serial0/0]fr interface-type dte  //配置帧中继接口类型为DTE,H3C路由器默认是DTE,所以可以省去这步

[RTB-Serial0/0]fr lmi type q933a   //配置LMI类型为Q933a

[RTB-Serial0/0]fr map ip 10.1.1.1 70  //配置通信对方(即RTA)的IP地址与本地DLCI号的映射

 

 

 

RTC的配置如下:

 

[RTC]interface s0/0

[RTC-Serial0/0]ip add 10.1.1.3 24

[RTC-Serial0/0]link-protocol fr

[RTC-Serial0/0]fr interface-type dte  //配置帧中继接口类型为DTE,H3C路由器默认是DTE,所以可以省去这步

[RTC-Serial0/0]fr lmi type q933a   //配置LMI类型为Q933a

[RTC-Serial0/0]fr map ip 10.1.1.1 30  //配置通信对方(即RTA)的IP地址与本地DLCI号的映射
