static routes

[Ludovit Koren]

Hi,

I realized on several different versions of FreeBSD including
5.4-STABLE, when using static routes to specific subnets and the WAN
link goes down for unpredictable reasons, the server gets ICMP
redirect message and rearranges routes to use default router. 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,
