They are never expired. Our default gateway (it's a HP switch) send ICMP redirect messages if it see a short path to destination. It's makes it not so overloaded. But pathes sometime changed. There is no problem with Windows workstations, they are rebooted daily. But my FreeBSD boxes hold dinamic route entries forever. I've looked through RFCs and Stevens' books and found no answer on what TTL for this entries. Now I just add route flush as cron job. But may be there is another way? -- Sem.
