      set dynamic-routing-redistribute as fdb,ip for logical switch, then neither ip nor fdb would be advertised

       Impact Assessment: Describe the severity and impact (e.g., network down,availability of a workaround, etc.).

      network down

       Software Versions: Specify the exact versions in use (e.g.,openvswitch3.1-3.1.0-147.el8fdp).

      ovn26.03-26.03.0-alpha.134.el9fdp.x86_64

        Issue Type: Indicate whether this is a new issue or a regression (if a regression, state the last known working version).

       

       Reproducibility: Confirm if the issue can be reproduced consistently. If not, describe how often it occurs.
