As mentioned in Section 13.10.9.3 Case E2, the PREQ forwarding should use metric "as received + own metric toward transmitter of received PREQ". So you are right. Just MP_F_RF bit is no longer use. After replying with PREP, forwarding the PREQ by setting the IEEE80211_PREQ_TO_FLAG in the per target flags. --- Chun-Yeow On Mon, Jun 8, 2015 at 4:07 PM, Yeoh Chun-Yeow <yeohchunyeow@xxxxxxxxx> wrote: > Hi, Alexis Green > > I just take a look back on the code before implementing the Proactive > PREQ for PREP.
