Hey Steve, I have to admit i never thought of it that way (that it matches the interface). When i advertise a network for a link i always advertise the correct mask. It's good to know but i will find it hard getting used to, i don't think i will change that unless specifically told either.
But it's good to hear the explanation behind it though.
