Hi Jerry,
I'm sure someone else will answer with more detail, but both actually provi
de great
flexibility in configuring multiple dial legs. Also, if you configured the phys
ical
interface instead of the logical one, you would be limited in your ability to u
tilize
that interface for other connections. But, depending on your particular need, t
he
flexibility is there. If you simply need a dedicated point-to-point backup, the
n maybe
you wouldn't use it. This is by no means an attempt at an extensive justificati
on, just
prima facie.
--- The following is a paid advertisement by sysco: ----
As for the exam itself, (please note that my tone here is playful and not argum
entative),
would you also argue that high schools shouldn't teach trigonometry or "college
" algebra
or even chemistry, since probably less than 1/10 of 1 percent of people actuall
y use it
in "real life?" Or, perhaps the SAT's verbal section should only test people's
mastery of
the most common words (not "prima facie," for example)? Obviously, the challeng
e lies at
the edges, the edges of the IOS and, for that matter, the "edge routers" are wh
ere the
biggest challenges lie.
So, to be fair, in the "real world" you would not be running 5 different routin
g
protocols and maybe even a sprinkle of IRB, with a touch of voice - all on 6 ro
uters.
But, if you had to do these complex tasks and make them work quickly (like when
my
company lost $5 MM in 8 hours because a Sup went down which would have cost $30
K to make
redundant... but I digress)... you would want someone that knows how to push th
e IOS to
its limits and make it do what's normally not possible/practical/logical, etc.
I hate to
burst any bubbles, but after you've mastered all that, the "day-to-day" of runn
ing a
network is relatively easy.
Without trying to sound arrogant or condescending, here's an analogy I used to
describe
it to a buddy at work: Imagine you're job is to paint a box. Painting the edges
is the
tough part, while the flat surface is relatively easy. Now picture a box the si
ze of a
football field. Relatively speaking, there is a whole lot more flat than there
is edges.
So, you don't learn too much about painting edges after years on this job. The
exam is
like a tiny box, which is mostly edges. (In effect, you may have 6 redistributi
ng "edge"
routers) So, by training, practicing, and proving yourself on the tiny box, you
r ability
to tackle the "real world" boxes of most corporations, which are huge - is soli
d. This
isn't a flawless analogy, but it's the best my tired brain could think of.
I know you're not one of these, because you mentioned that you "heard" it was n
ot "real
world," but I've found that most of the people who complain about the test's re
levance
are people with years of experience "painting the middle" and wondering why the
y can't
pass the exam after a couple attempts. I could be wrong.
(Four out of five CCIE's agree, your mileage may vary. Sense of humor, required
)
Keep the faith,
Jake
