Actually, RFC 3484 would be the preferred mechanism over configuring every application.

Application specific address binding should only be used for applications that need an exception to the host-wide source address selection choice.

	+	Fewer surprises for your ops team
	+	Lower probability of a mistake leading to incorrect source address selection
	+	Reduced probability of configuration mistake time-bombs
	+	Reduces the amount of configuration required for a host
