實(shí)驗(yàn)拓?fù)鋱D如下:
圖中路由器及幀中繼交換機(jī)均由3640實(shí)現(xiàn),三個(gè)路由器都用S0/0跟FRsw相連
R1 s0/0 ip 192.168.1.1 /24
R2 s0/0 ip 192.168.1.2 /24
R3 s0/0 ip 192.168.1.3 /24 
    
先對(duì)FR交換機(jī)進(jìn)行配置
----FRsw
FRsw(config)#frame-relay switching 開(kāi)啟幀中繼交換功能
FRsw(config)#interface s0/0
FRsw(config-if)#no shutdown
FRsw(config-if)#no ip address 關(guān)閉接口IP地址
FRsw(config-if)#encapsulation frame-relay 封閉幀中繼
FRsw(config-if)#frame-relay lmi-type cisco配置LMI類型
FRsw(config-if)#frame-relay intf-type dce配置接口類型
FRsw(config-if)#clock rate 64000 配置時(shí)鐘頻率
FRsw(config-if)#frame-relay route 102 interface s0/1 201
FRsw(config-if)#frame-relay route 103 interface s0/2 301

配置該本地端口DLCI值及虛鏈路對(duì)應(yīng)出口和對(duì)端DLCI值
FRsw(config-if)#exit

-------------------------------語(yǔ)句說(shuō)明參考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

-------------------------------語(yǔ)句說(shuō)明參考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鏈路狀態(tài)
#show frame-relay route 
 
由于串行鏈路上的對(duì)端還未進(jìn)行配置及聯(lián)接,PVC鏈路還處于未激活狀態(tài).

下面進(jìn)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 接口封裝幀中繼
R1(config-if)#no frame-relay inverse-arp關(guān)閉反向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
配置對(duì)端IP與本地DLCI映射

----R2(語(yǔ)句說(shuō)明參考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(語(yǔ)句說(shuō)明參考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

再次查看FRsw的狀態(tài)
#show frame-relay route

所有PVC鏈路已經(jīng)全部處于激活狀態(tài) 試驗(yàn)聯(lián)通性,在R1上分別ping R2和R3的S0/0口IP地址
 
R2 ping R3
