    <p>Hi Shanshan,</p>
    Can you be more specific on the why and when you want to resend an
    Interest to the same outgoing face?<br>
    <br>
    Teng<br>

      <div>I read the latest version of the nfd-developer-guide and I am
        not sure if it is allowed to retry the same Interest (generated
        by the local node rather than the consumer) via the same
        outgoing face. </div>
