Node(s) CPU architecture, OS, and Version: Linux ali-f-tair-vm-20-26 3.10.0-1160.114.2.el7.x86_64 #1 SMP Wed Mar 20 15:54:52 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

Cluster Configuration: 1 server, 1 agent

Describe the bug:
To put it simply, the node where the Pod is located is 1.1.1.1. Pinging 1.1.1.1 in the Pod does not work, but pinging any other node such as 1.1.1.2 works.

A new machine with a single network card was added, and the host machine to which the sleep-27 pod request belongs is OK. The GPU machine has multiple network cards, and the host machine to which the sleep pod request belongs is not connected.
