It was just a preference in some of them. Habit. But if it is not called out it doesn't matter.

Is the "best practise" to use the loopback interface if available on the router, even if no mention is made in the task about it? The reason will be for interface failure (I think), which in this case will not be true as there is only one physical interface. Thanks Johan
