There are good reasons for this; not the least of which being that
between obtaining such advice and actually committing to a decision
based on that advice, the validity of the advice may expire due to
changes in the system's topology.
I realise this doesn't help you much, but telling the future is a
tough business. 8(
Thanks for the reply.
The conditions under which the system's topology might change (DHCP
server says to, user unplugs ethernet cable, cordless phone/microwave
interferes with wireless network and causes loss of connectivity,
etc.) are all possibilities I'll have to live with. Knowing the
future would certainly be helpful, but I'm content with knowing how
it would proceed if it were to happen presently.
Is there no KPI interface for asking the routing table for the
gateway ip address for a given destination address?
