I think your comment just let me find a bug in olsrd. In file "src/lq_packet.c"
the TTL list for fisheye metric is defined as

   static int ttl_list[] = { 2, 8, 2, 16, 2, 8, 2, MAX_TTL};

Wouldn't it be better to make it this way, so the first TC of a node
can update the whole network ?

   static int ttl_list[] = { MAX_TTL, 2, 8, 2, 16, 2, 8, 2 };

If not it might take multiple TCs until you even reach parts of the
network the first time.
