  四、 帧中继的流量整形
  实验拓扑
  
  
  1. 在还没进行下面的实验以前,先用扩展ping命令:
  RouterA#ping
  Protocol [ip]:
  Target IP address: 192.168.2.1
  Repeat count [5]: 55
  Datagram size [100]: 1111
  Timeout in seconds [2]:
  Extended commands [n]: y
  Source address or interface: 192.168.1.1
  Type of service [0]:
  Set DF bit in IP header? [no]:
  Validate reply data? [no]:
  Data pattern [0xABCD]:
  Loose, Strict, Record, Timestamp, Verbose[none]:
  Sweep range of sizes [n]:
  Type escape sequence to abort.
  Sending 55, 1111-byte ICMP Echoes to 192.168.2.1, timeout is 2
  seconds:
  !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  Success rate is 100 percent (55/55), round-trip min/avg/max =
  176/179/192 ms
  记录下他们的返回时间;
  2. 在同一条pvc之间(如RouterARouterB)创建一个map-class,定义pvc的CIR(committed information rate)命令如下:
  RouterA(config)#map-class frame-relay CIR
  RouterA(config-map-class)#frame-relay traffic-rate 2000
  RouterB(config)#map-class frame-relay CIR
  RouterB(config-map-class)#frame-relay traffic-rate 2000
  3. 将该map-class应用到端口上:
  RouterA(config)#interface serial 0
  RouterA(config-if)#frame-relay traffic-shaping
  RouterA(config-if)#interface serial 0.1 multipoint
  RouterA(config-subif)#frame-relay class CIR
  
  RouterB(config)#interface serial 0
  RouterB(config-if)#frame-relay traffic-shaping
  RouterB(config-if)#interface serial 0.16 point-to-point
  RouterB(config-subif)#frame-relay class CIR
  
  4. 用show frame-relay pvc验证CIR的配置;
  5. 再一次用扩展ping命令,验证返回的时间是否比原来的要长?
