[Xorp-hackers] OSPF on high latency links

Hi all,

I have a problem with ospf loosing connection over high latency links. The
link in question will induce a delay from minimum 1 sec to a maximum of more
than 20 sec. (Yes, such links do exist:-/ )

I have tried to set the hello and router-dead intervals to 60 and 240
respectivly, but I still loose the connection.

I have also tried to manipulate transmit-delay and retransmit in order to
handle the latency (20 and 90secs) but no luck so far.

Can anybody tell me why this happens, or at least what I can do to make ospf
a bit more forgiving about delayed packages (If that is the problem...)?

Thanks in advance,
