并不是等价的功能,traceroute --mtu 可以直接检测到链路上 MTU 降低的地方

$ traceroute -n --mtu 6.0.255.1
traceroute to 6.0.255.1 (6.0.255.1), 30 hops max, 65000 byte packets
 1  192.168.0.1  0.163 ms F=1500  0.065 ms  0.053 ms
 2  6.0.0.18  1.125 ms F=1476  0.889 ms  0.817 ms
 3  6.0.0.33  1.484 ms  1.412 ms  1.447 ms
 4  6.0.0.58  3.387 ms F=1420  12.781 ms  2.690 ms
 5  6.0.255.1  3.448 ms  3.806 ms  4.568 ms
