I suppose this depends on what your cluster is doing and how it is running. If you have a fairly simple service of some sort and a service IP address that all the clients connect to, then I would worry that setting up a default gateway in advance my confuse the non-active node. You may be better setting this when the fail-over is triggered and after the IP address has been assigned to the new active node.
