第一步：在R1上配置帧中继
R1(config)#int s3/0
R1(config-if)#en
R1(config-if)#encapsulation frame-relay （封装为帧中继）
R1(config-if)#no frame-relay inverse-arp （关闭自动映射，关闭反向arp）
R1(config-if)#frame-relay map ip 192.168.0.2 102 broadcast
R1(config-if)#exit
第二步：检查 frame-relay映射 R1#sh frame-relay map Serial3/0 (up): ip 192.168.0.2 dlci 102(0x66,0x1860), static, broadcast, CISCO, status defined, active 第三步：在R2上配置帧中继 R2(config-if)#en R2(config-if)#encapsulation frame-relay R2(config-if)#no frame-relay inverse-arp R2(config-if)#frame-relay map ip 192.168.0.1 201 broadcast R2(config-if)#no sh R2(config-if)#exit R2(config)# 第四步：在R2上查看frame-felay 映射关系 R2#sh fr R2#sh frame-relay map Serial3/0 (up): ip 192.168.0.1 dlci 201(0xC9,0x3090), static, broadcast, CISCO, status defined, active
