If you want to have two servers handle a request in lockstep, you need
to duplicate it. Pretty much by definition.

If you have the switches do the duplication, you save having to buy a
dedicated duplication appliance ("load balancer") which itself can be a
single point of failure. This use was not foreseen in RFC 1812, which is
hardly surprising; many other features which we take for granted today
were not foreseen back then. The only problem is that no one bothered to
get RFC 1812 updated -- an obvious job for e.g. Stonesoft or Check
Point.
