Re: DNS resolution order with multihomed host

Hello Kevin,

The reason why we want this dns names to be resolved always in
the same order is that we have two data connections with our
remote datacenter: one through frame relay and one through Internet, and we
have to be connected pemanently with 2 machines there.

This machines have 2 IPs: one private through frame relay and one public
through Internet.

We want to access them with the private IP (10.x.x.x) through the frame
relay while it si possible. But if the frame relay fails we want to access
them
with the public IP (194.x.x.x) through Internet.

So, as you can see, we want to have two IPs on these machines as a fault
tolerant mechanism. If the first IP isn't reachable our system uses the
second.

¿What do you think about our topology?

Thank you very much.
Best Regards.

Daniel P.
