mmm it seems we are not using buggy driver because our node are ubiquity picostation with madwifi, moreover we have the same message from eth0 ( wired interface ) ... and not seems we have loop in every node... and now mdns is disabled and we continue to have the same message... here is the realtime topology:<br>

<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">this is a warning that olsrd received the exactly same packet from one of its neighbor more than once,..<br>
infact olsrd received a packet with an seqnr which is identical to the previous packet,..<br><div><br></div><div>known cause for example is the buggy wireless driver of routeros (if u use for example use wds links (with bad signal) between mikrotik routerboards you will get duplicate packets seldomly)</div>
<div>or maybe you built a layer 2 loop, or found another buggy hardware/device driver,..</div><div>mdns might also produce duplicates</div><div><br></div><div>btw: olsrd versoins that report this, are not affected by duplicate olsr packets (they ignore the duplicate), but older olsrd versions interprete a duplicate packet as extreme packet loss (65535 packets lost *G) and will set the links lq to 0,... </div>
<div><br></div><div>as you get many erros of this type, i recommend to find out what causes it, as other software may also react bad on duplicates</div><div><br></div><div>Markus<br><br><div class="gmail_quote"><div><div>
