Then all the traffic is routed to the default router even the WAN link is again up. Other unix like system (HP-UX, Linux) do not act the way, i.e. they do not change static routes. Should not be ignored the ICMP redirect messages concerning static routes? Thank you very much in advance. Regards, lk
