automatic refresh of route table ?

[Jim Giles]

Our network folks make changes in the network (remove switches etc.)that requires me to do a route flush from time to time to enable connections to function. Is there anything to configure that will force the route tables to refresh automatically without blowing away the default route? Is there a "timeout" feature for the route entries.

I do not run either routed or gated.

[Al Licause]

Could you please be a bit more specific about
the types of routes that you are trying to
flush ?

Without running gated or routed, the only type
of route entry that I am aware of that can be
dynamically updated is an icmp redirect. These
will show up with 'D' or 'M' in the flag field
which indicate reDirector or Modified redirect.

By default it later versions of tru64unix they don't timeout, but there is a parameter that can be set to either ignore them or allow them to timeout.

Both parameters are in the inet subsystem
as seen by sysconfig -q inet.

They are icmp_rejectcodemask and
icmp_redirecttimeout. See man sys_attrs_inet for further details.

Setting icmp_rejectcodemask to 32 decimal
tells the system to ignore these messages.
