Thanks for your answer. I did not consider layer 2 in my assumptions.<br><br>Problem solved :)<br><br>>> For example, the MPR of A in this scenario is B, then it will be the next<br>>> hop in OLSR internal routing table but in kernel routing table we just know<br>
>> that we have to send this message for the interface X.<br>><br>> this is not correct.<br>><br>> from the routing table you know the IP address of your next hop, not<br>> just the interface to send the packet out.<br>
><br>> you then use the ARP protocol to discover the Mac address of the next<br>> hop, and you will send a 802.11 frame that is unicast for your next<br>> hop and will be discarded from other station that overhear the frame<br>
