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
