可以查看一下帧中继映射表，查看一下映射关系

R2可以采用两种配置方式
第一种：直接在物理端口上配置
R2(config)#int s1/0
R2(config-if)#encapsulation frame-relay
R2(config-if)#ip address 12.12.12.21 255.255.255.0
R2(config-if)#no frame-relay inverse-arp
R2(config-if)#no arp frame-relay
R2(config-if)#frame-relay map ip 12.12.12.12 201 #这里只能使用frame-relay map，不能够使用frame-relay interface-dlci。
R2(config-if)#no shutdown
R2(config-if)#end
R2(config-if)#encapsulation frame-relay
R2(config-if)#ip address 12.12.12.21 255.255.255.0
R2(config-if)#no frame-relay inverse-arp
R2(config-if)#no arp frame-relay
R2(config-if)#frame-relay map ip 12.12.12.12 201 #这里只能使用frame-relay map，不能够使用frame-relay interface-dlci。
R2(config-if)#no shutdown
R2(config-if)#end
第二种：在子接口上配置
R2(config-if)#int s1/0.1 multipoint #这里指定点对点和点对多点均可，可根据实际需要设置
R2(config-subif)#ip address 12.12.12.21 255.255.255.0
R2(config-subif)#frame-relay interface-dlci 201 #这里也可以使用frame-relay map
R2(config-fr-dlci)#exit
R2(config-subif)#exit
R2(config-subif)#ip address 12.12.12.21 255.255.255.0
R2(config-subif)#frame-relay interface-dlci 201 #这里也可以使用frame-relay map
R2(config-fr-dlci)#exit
R2(config-subif)#exit
