    * Check the routing entries throughout the path from L1 to r2 (and
    the reverse).<br>
    * use tcpdump on r1 and r2 to see where the ICMP packets are being
    dropped<br>

                  Hello everyone,<br>
                  I have configured 3 routers r1 r2 and laptop with
                  olsrd on adhoc mode. The topology is as shown below.<br>
                     r1  <-->  r2  <-->  laptop<br>
                  r1 can see r2 but not laptop and r2 can see both. When
                  i started olsrd r1 could not ping laptop but it could
                  ping r2 and same with laptop. I even enabled
                  forwarding on r2 but still with the same results. So
                  Is there any way to solve this??<br>

            Is this problem similar to the one you have posted and
            resolved earlier (pl. see the following URL)?<br>

            Did you try the same debugging steps suggested then by
            Henning?<br>
