我在云中运行了三台 Ubuntu 服务器（虚拟），它们都位于同一个虚拟 LAN 中，配置了类似的规格。但是，当我tracepath在这三台主机上运行到特定目标主机时，其中一台出现了奇怪的输出，too many hops而其他两台可以通过 2 跳到达目标。
事实上，所有跳数都应该相同，您知道这里可能存在什么问题吗？网络堆栈是否需要重新启动？
在职的：
root@xx-yy-zz-02:~# tracepath target.mail.com
1?: [LOCALHOST] pmtu 1500
1: 192.168.32.2 1.797ms
1: 192.168.32.2 1.694ms
2: target.mail.com 3.075ms reached
Resume: pmtu 1500 hops 2 back 2
不工作：
root@xx-yy-zz-01:/var/log# tracepath target.mail.com
1?: [LOCALHOST] pmtu 1500

Too many hops: pmtu 1500
Resume: pmtu 1500
两个主机上的路由配置看起来相同，网络团队指向虚拟服务器本身。
