Howard,
I do not believe you have gone too far. You have simply provided
some extra details that some of us may be interested in. There may
may be some on this list that are interested in more detailed
information
along the way to their CCIE
just my .02

Hey, Howard.
I always admire your posts. :)
But as you admitted at the bottom of your own post, I'm afraid you've
gone too far here.
I think that's the difference between the requirements for
administrators and those for implementors in general.
When I read some RFC stuffs, I'm always having this kind of confusion.
Do we ever really need such in-depth knowledge that may be useful only
to real protocol implementors?
Yes, it will help us when we know every detail of ins and outs of
protocols, I know that.
But we're already behind the schedule to cover ever expanding variety of
networking subjects.
Anyway, thanks for your insights.
Jaeheon
