	A L3 switch is still one virtual machine with one routing
	entry and one path from the customer to the L3 switch.

	There is no need to play this silly game.  It just make
	things harder.  Some machines will make assumptions that
	all the address refer to one machine and that some operations
	shouldn't be retried because they won't get a different
	response.
