CCIE分解:帧中继子接口和流量整形（Traffic Shaping）配置
实验说明：
R1和R2之间的平均吞吐量较低为了节省开支，我们决定修改与服务提供商签署的合同，将约定信息速率从1.544Mbit/s降低到19.2Mbit/s
实验过程：
第一步：预配置、
R1(config)#int s3/0
R1(config-if)#encapsulation frame-relay
R1(config-if)#no frame-relay inverse-arp
R1(config-if)#no sh
R1(config-if)#end
R1(config)#int s3/0.1 point-to-point //配置为点到点子接口
R1(config-subif)#no sh
R1(config-subif)#ip ad 192.168.12.1 255.255.255.0
R1(config-subif)#no frame-relay inverse-arp //关闭反向ARP
R1(config-subif)#frame-relay interface-dlci 102
R1(config-subif)#exit
R1(config)#router ospf 1
R1(config-router)#net 0.0.0.0 0.0.0.0 area 0
R1(config-router)#exit
R1(config)#int s3/0.2 point-to-point
R1(config-subif)#no sh
R1(config-subif)#no frame-relay inverse-arp
R1(config-subif)#ip ad 192.168.13.1 255.255.255.0
R1(config-subif)#no sh
R1(config-subif)#frame-relay interface-dlci 103
R2(config)#int s3/0
R2(config-if)#encapsulation frame-relay
R2(config-if)#ip ad 192.168.12.2 255.255.255.0
R2(config-if)#no sh
R2(config-if)#frame-relay map ip 192.168.12.1 201 broadcast
R2(config-if)#exit
R2(config)#router ospf 1
R2(config-router)#net 0.0.0.0 0.0.0.0 area 0
R2(config-router)#exit
R2(config)#int s3/0
R2(config-if)#ip ospf network point-to-point
R3(config)#int s3/0
R3(config-if)#no sh
R3(config-if)#encapsulation frame-relay
R3(config-if)#no frame-relay inverse-arp
R3(config-if)#ip ad 192.168.13.3 255.255.255.0
R3(config-if)#no sh
R3(config-if)#frame-relay map ip 192.168.13.1 301 b
R3(config-if)#exit
R3(config)#router ospf 1
R3(config-router)#net 0.0.0.0 0.0.0.0 area 0
R3(config-router)#exit
R3(config)#int s3/0
R3(config-if)#ip ospf network point-to-point
实验过程：
第一步在R1 进行流量整形
R1(config)#map-class frame-relay CIR
R1(config-map-class)#frame-relay traffic-rate 19200
R1(config-map-class)#exit
R1(config)#int s3/0
R1(config-if)#frame-relay traffic-shaping
R1(config-if)#int s3/0.1
R1(config-subif)#frame-relay class CIR
R1(config-subif)#int s3/0.2
R1(config-subif)#frame-relay class CIR
第二步：在R2上进行流量整形。
R2(config)#map-class frame-relay CIR
R2(config-map-class)#frame-relay traffic-rate 19200
R2(config-map-class)#exit
R2(config)#int s3/0
R2(config-if)#frame-relay class CIR
第三步：查看更为详细的流量整流的统计结果
