Re: OSPF Backbone Area Clarification

Believe it or not, people that design solutions try to make it as easy
as possible. Given that you will always have only one backbone, it's
easier to have it fixed than to have yet another parameter to configure.

On a more conceptual side, design decisions are made in a context that
is not always readily available, so even though it's nice to know why
something is done one way or the other, sometimes the answer is just
"because someone decided to do it so".

Moy could have thought: hey, if someone starts with area 1.1.1.1 and
then joins area 2.2.2.2, he might want to pick which one to become
backbone. It seems he did not.
