每當我運行 時mtr，它都會簡要顯示每行一個躍點，然後在到達最後一個躍點時，它在所有其他躍點上顯示為重複條目：
My traceroute [v0.92]
[local hostname] ([local ip]) 2019-10-17T12:40:35-0300
Keys: Help Display mode Restart statistics Order of fields quit

[ip]
4. [ip] 0.0% 3 0.6 0.7 0.6 0.8 0.1
這不會發生在traceroute：
$ traceroute [domain]
traceroute to [domain] ([ip]), 30 hops max, 60 byte packets
1 [ip1] ([ip1]) 1.369 ms 1.322 ms 1.309 ms
2 [ip2] ([ip2]) 1.248 ms 1.218 ms 1.196 ms
3 [ip3] ([ip3]) 38.997 ms 38.988 ms 39.416 ms
4 [ip] ([ip]) 1.034 ms 1.005 ms 0.973 ms
這裡發生了什麼事？
