      This is a clone of issue OCPBUGS-12971. The following is the description of the original issue:

      Description of problem:

      hybrid-overlay on Windows nodes ignores existing non-persistent routes when creating the new vNIC. This becomes an issue especially on AWS where non-persistent routes are used for the local metadata server which is in turn used by the kubelet.
      How reproducible:{code:none}
      Always on Windows Server 2022 instances on AWS

      Steps to Reproduce:

      1. Bring up an hybrid-ovn OCP cluster on AWS
      2. Add a Windows Server 2022 Machine or BYOH instance

      Actual results:

      The Windows Server 2022 node goes to NotReady

      Expected results:

      The Windows Server 2022 node goes to Ready

      Additional info:

      While this problem shows up only on AWS, it can be an issue on other providers if customers are depending on non-persistent routes on Windows nodes in general.
