第四步：用扩展ping命令测试路由之间的连通性，发送几个大数据包（超过1000字节的数据包），测试吞吐量，注意以毫秒计的返回时间
Protocol [ip]:
Target IP address: 192.168.12.2
Repeat count [5]: 55
Datagram size [100]: 1111
Timeout in seconds [2]:
Extended commands [n]: y
Source address or interface: 192.168.12.1
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 Echos to 192.168.12.2, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Success rate is 100 percent (55/55), round-trip min/avg/max = 52/557/1120 m
第五步：在R1进行Frame-relay流量×××
R1#conf
Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line. End with CNTL/Z.

R1(config)#map-class fram
R1(config)#map-class frame-relay cir
R1(config-map-class)#fram
R1(config-map-class)#frame-relay tra
R1(config-map-class)#frame-relay traffic-rate 19200
R1(config-map-class)#exit
R1(config)#int s3/0
R1(config-if)#fram
R1(config-if)#frame-relay tra
R1(config-if)#frame-relay traffi
R1(config-if)#frame-relay traffic-shaping
R1(config-if)#int s3/0.2
R1(config-subif)#fram
R1(config-subif)#frame-relay class
R1(config-subif)#frame-relay class cir
R1(config-subif)#^Z
第六步：在R2上进行Frame-relay流量×××
R2(config)#map
R2(config)#map-cl
R2(config)#map-class fram
R2(config)#map-class frame-relay cir
R2(config-map-class)#fram
R2(config-map-class)#frame-relay traff
R2(config-map-class)#frame-relay traffic-rate 19200
R2(config-map-class)#exit
R2(config)#int s3/0
R2(config-if)#frame
R2(config-if)#frame-relay class cir
R2(config-if)#^Z

Sweep range of sizes [n]:
Type escape sequence to abort.
Sending 55, 1111-byte ICMP Echos to 192.168.12.2, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Success rate is 100 percent (55/55), round-trip min/avg/max = 52/557/1120 m
