.
实验过程：
第一步：在R1上进行配置
R1(config)#int s3/0
R1(config-if)#en fr
R1(config-if)#no sh
R1(config-if)#no fr inverse-arp
R1(config-if)#exit
R1(config)#int s3/0.1 point-to-point
R1(config-subif)#ip add 12.0.0.1 255.255.255.0
R1(config-subif)#frame-relay interface-dlci 102（指定dlci号，这是必须的）
R1(config-fr-dlci)#exit
R1(config)#int s3/0.2 point-to-point
R1(config-subif)#ip add 13.0.0.1 255.255.255.0
R1(config-subif)#frame-relay interface-dlci 103
R1(config-subif)#end
第二步：现在查看Frame-relay映射关系
R1#sh fr map
Serial3/0.1 (up): point-to-point dlci, dlci 102(0x66,0x1860), broadcast
status defined, active
Serial3/0.2 (up): point-to-point dlci, dlci 103(0x67,0x1870), broadcast
status defined, active
R1#
第三步：在R2上进行配置
R2(config)#int s3/0
R2(config-if)#en fr
R2(config-if)#no fr inverse-arp
R2(config-if)#frame-relay map ip 12.0.0.1 201 b
R2(config-if)#ip add 12.0.0.2 255.255.255.0
R2(config-if)#no sh
R2(config-if)#exit
第四步：在R3上进行配置
R3(config)#int s3/0
R3(config-if)#en fr
R3(config-if)#no sh
R3(config-if)#no frame-relay inverse-arp
R3(config-if)#frame-relay map ip 13.0.0.1 301 b
R3(config-if)#ip add 13.0.0.3 255.255.255.0
R3(config-if)#exit
第五步：在R1、R2、R3上配置EIGRP协议并关闭自动汇总
R1(config)#router eigrp 11
R1(config-router)#net 12.0.0.0
R1(config-router)#net 13.0.0.0
R1(config-router)#net 1.1.1.0
R2(config)#router eigrp 11
R2(config-router)#net 12.0.0.0
R2(config-router)#net 2.2.2.0
R3(config)#router eigrp 11
R3(config-router)#net 3.3.3.0
R3(config-router)#net 13.0.0.0
第六步：查看R1、R2、R3的路由表
