Frame Relay Lab實作

其中R2模擬為訊框中繼交換機、R1與R3為一般Router
R2訊框中繼交換機的設定
R2#configure t
R2(config)#frame-relay switching
#啟用訊框中繼交換機功能
R2(config)#interface ser0/0
R2(config-if)#encapsulation frame-relay
R2(config-if)#int ser0/1
R2(config-if)#encapsulation frame-relay
R2(config-if)#int ser0/0
R2(config-if)#frame-relay intf-type dce
#讓這個界面成為訊框中繼的DCE界面，這與路由器的DCE介面是不同的
R2(config-if)#frame-relay route 102 interface ser0/1 201
#如果從PVC 102收到訊框，就利用PVC 201從int s0/1傳送出去
R2(config-if)#clock rate 64000
#讓界面成為DCE裝置端，這與訊框中繼的DCE不同
R2(config-if)#no shutdown

R2(config-if)#int ser 0/1
R2(config-if)#frame-relay intf-type dce
R2(config-if)#frame-relay route 201 interface ser0/0 102
##如果從PVC 201收到訊框，就利用PVC 102從int s0/0傳送出去
R2(config-if)#clock rate 64000
R2(config-if)#no shutdown
R2(config-if)#end

R1的frame relay設定
R1#configure t
R1(config)#interface ser0/0
R1(config-if)#encapsulation frame-relay
R1(config-if)#no shutdown
R1(config-if)#int s0/0.102 point-to-point
R1(config-subif)#ip address 172.16.10.1 255.255.255.0
R1(config-subif)#frame-relay interface-dlci 102
R1(config-fr-dlci)#exit
R1(config-subif)#exit

R3的frame relay設定
R3#configure t
R3(config)#int s0/0
R3(config-if)#encapsulation frame-relay
R3(config-if)#no shutdown
R3(config-if)#int s0/0.201 point-to-point
R3(config-subif)#ip address 172.16.10.2 255.255.255.0
R3(config-subif)#frame-relay interface-dlci 201
R3(config-fr-dlci)#end

R1設定default route
R1#configure t
R1(config)#interface fa1/0
R1(config-if)#ip address 192.168.10.1 255.255.255.0
R1(config-if)#no shutdown
R3(config-if)#exit
R1(config)#ip route 0.0.0.0 0.0.0.0 172.16.10.2
R1(config)#end

R3設定default route
R3#configure t
Enter configuration commands, one per line. End with CNTL/Z.
R3(config)#int
R3(config)#interface fa1/0
R3(config-if)#ip address 192.168.20.1 255.255.255.0
R3(config-if)#no shutdown
R3(config-if)#exit
R3(config)#ip route 0.0.0.0 0.0.0.0 172.16.10.1
R3(config)#end
