先对FR交换机进行配置

 

----FRsw
FRsw(config)#frame-relay switching          开启帧中继交换功能
FRsw(config)#interface s0/0
FRsw(config-if)#no shutdown                              
FRsw(config-if)#no ip address                       关闭接口IP地址
FRsw(config-if)#encapsulation frame-relay     封闭帧中继
FRsw(config-if)#frame-relay lmi-type cisco    配置LMI类型
FRsw(config-if)#frame-relay intf-type dce      配置接口类型
FRsw(config-if)#clock rate 64000                  配置时钟频率
FRsw(config-if)#frame-relay route 102 interface s0/1 201
FRsw(config-if)#frame-relay route 103 interface s0/2 301
配置该本地端口DLCI值及虚链路对应出口和对端DLCI值
FRsw(config-if)#exit
 
-------------------------------语句说明参考S0/0接口配置
FRsw(config)#interface s0/1
FRsw(config-if)#no shutdown
FRsw(config-if)#no ip address
FRsw(config-if)#encapsulation frame-relay
FRsw(config-if)#frame-relay lmi-type cisco
FRsw(config-if)#frame-relay intf-type dce
FRsw(config-if)#clock rate 64000
FRsw(config-if)#frame-relay route 201 interface s0/0 102
FRsw(config-if)#frame-relay route 203 interface s0/2 302
FRsw(config-if)#exit
 
-------------------------------语句说明参考S0/0接口配置
FRsw(config)#interface s0/2
FRsw(config-if)#no shutdown
FRsw(config-if)#no ip address
FRsw(config-if)#encapsulation frame-relay
FRsw(config-if)#frame-relay lmi-type cisco
FRsw(config-if)#frame-relay intf-type dce
FRsw(config-if)#clock rate 64000
FRsw(config-if)#frame-relay route 301 interface s0/0 103
FRsw(config-if)#frame-relay route 302 interface s0/1 203
FRsw(config-if)#exit
 
查看PVC链路状态
#show frame-relay route

由于串行链路上的对端还未进行配置及联接,PVC链路还处于未激活状态.
 
下面进行DTE端路由器配置
----R1
R1(config)#interface s0/0
R1(config-if)#ip address 192.168.1.1 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#encapsulation frame-relay      接口封装帧中继
R1(config-if)#no frame-relay inverse-arp    关闭反向ARP           
R1(config-if)#frame-relay map ip 192.168.1.2 102 broadcast
R1(config-if)#frame-relay map ip 192.168.1.3 103 broadcast
                                            配置对端IP与本地DLCI映射
 
----R2(语句说明参考R1)
R2(config)#interface s0/0
R2(config-if)#ip address 192.168.1.2 255.255.255.0
R2(config-if)#no shutdown
R2(config-if)#encapsulation frame-relay
R2(config-if)#no frame-relay inverse-arp
R2(config-if)#frame-relay map ip 192.168.1.1 201 broadcast
R2(config-if)#frame-relay map ip 192.168.1.3 203 broadcast
 
----R3(语句说明参考R1)
R3(config)#interface s0/0
R3(config-if)#ip address 192.168.1.3 255.255.255.0
R3(config-if)#no shutdown
R3(config-if)#encapsulation frame-relay
R3(config-if)#no frame-relay inverse-arp
R3(config-if)#frame-relay map ip 192.168.1.1 301 broadcast
R3(config-if)#frame-relay map ip 192.168.1.2 302 broadcast
