UNREACHABLE messages imply some kind of real failure or pathology (congestion), not that someone simply hasn't gotten an ARP back. I understand that they may not want to hang on to a packet because of buffering, so they can simply drop it silently. Telling someone the host is unreachable is simply not true in your example. -Mike O'Dell
