2 node cluster

Hi,

I would like to configure a 2 node cluster where each machine has a
unique IP address and both are accessible at the same time (via round
robin DNS).

I would like it so that if one machine went down the other would take
over its IP address... this, i would imagine, would involve 2
clusters... one with machine 1 as the primary and machine 2 secondary,
and one with machine 2 as the primary and machine 1 secondary.

Is this possible and if so could someone send me an example config?

Cheers,

Dan.
