以下为使用GNS3模拟器起帧中继的一个简单实验：
帧中继交换机R1 ! ! frame-relay switching ! ! interface Serial1/0 no ip address encapsulation frame-relay serial restart-delay 0 clock rate 64000 frame-relay lmi-type ansi （三种: ciscoansiq933a） frame-relay intf-type dce frame-relay route 102 interface Serial1/1 201 (route + 本地DLCI +出口 +对方DLCI) frame-relay route 103 interface Serial1/2 301 ! interface Serial1/1 no ip address encapsulation frame-relay serial restart-delay 0 clock rate 64000 frame-relay lmi-type ansi frame-relay intf-type dce frame-relay route 201 interface Serial1/0 102 frame-relay route 304 interface Serial1/2 403 ! interface Serial1/2 no ip address encapsulation frame-relay serial restart-delay 0 clock rate 64000 frame-relay lmi-type ansi frame-relay intf-type dce frame-relay route 301 interface Serial1/0 103 frame-relay route 403 interface Serial1/1 304 ! R2 ! interface Serial1/0 ip address 10.0.0.2 255.255.255.0 encapsulation frame-relay serial restart-delay 0 frame-relay map ip 10.0.0.4 103（对方IP+本地DLCI）frame-relay map ip 10.0.0.3 102 no frame-relay inverse-arp(不关反向ARP的话，可以动态学习到对方，那么就不用配置frame-relay map ip)end R3 ! interface Serial1/1 ip address 10.0.0.3 255.255.255.0 encapsulation frame-relay serial restart-delay 0 frame-relay map ip 10.0.0.4 304 frame-relay map ip 10.0.0.2 201 no frame-relay inverse-arp end R4 ! interface Serial1/2 ip address 10.0.0.4 255.255.255.0 encapsulation frame-relay serial restart-delay 0 frame-relay map ip 10.0.0.2 301 frame-relay map ip 10.0.0.3 403 no frame-relay inverse-arp end 查看映射show frame-relay map
