    实验测试:

    R1#ping 192.168.1.10

    Type escape sequence to abort.

    Sending 5, 100-byte ICMP Echos to 192.168.1.10, timeout is 2 seconds:
    !!!!!

    Success rate is 100 percent (5/5), round-trip min/avg/max = 64/146/340 ms

    R1#ping 192.168.1.20

    Type escape sequence to abort.

    Sending 5, 100-byte ICMP Echos to 192.168.1.20, timeout is 2 seconds:

    !!!!!
    Success rate is 100 percent (5/5), round-trip min/avg/max = 60/117/232 ms

    R1#ping 192.168.2.10

    Type escape sequence to abort.

    Sending 5, 100-byte ICMP Echos to 192.168.2.10, timeout is 2 seconds:
