Hey Nate,
I spent a disproportionate amount of my study time trying to get to that
magical place where I could stare down any redistribution task of any
complexity and just see what was going to happen underneath the hood (bonnet
for our international list members). Never happened. What did happen was
that 'debug ip routing' became a really good friend of mine. Also, just
running full speed and smacking myself into that wall over and over again
helped. I'm now to the point where I feel I can solve any redistribution
task of any complexity - GIVEN ENOUGH TIME to do so. But sometimes it's so
subtle that you're not likely to see it until you get some results from your
debug. There were a few times when I even adjusted the AD of a given
protocol or something like that just to see what, if any, impact it might
have. That may or may not have sent me in a new direction.
Don't let these discourage you like I did. Keep at it. Realize that no
sane network engineer would really do what some of these lab scenarios are
calling for. They're just meant to expose various (often times unintuitive)
behaviors that you might at some point encounter.
Regards,
Scott

Subject: Quick and dirty way to identify issues regarding redistribution
Guys,
So i ran into a brick wall last night which is IE's Workbook 3 Lab 8
(Thanks Brians!). I thought i was really starting to get into the
groove and this took me down a peg.
With that said i actually ran into the section near the end where the
redistribution happened. I was sitting in front of my routers just
absolutely dumfounded and saved the configs and quit the lab early.
I have listened to a few VOD's, did all of the basic lab scenarios
regarding redistribution and even can deal with redistribution in a
typical "i have two routers and they both have EIGRP and OSPF talking
and you need to redistribute on both questions", so i think i got the
BASIC jist of it down.
Is there a methodolgy the truly experienced use to see the big
picture with extremely complex redistribution. Maybe like a playbook
one uses. I have read some folks tag their redistributed routes,
others will allow redistribution on one router and immediately
disallow on the second.. maybe a combination of both.
Any suggestions on getting a truly in-depth understanding of
redistribution would be extremely helpful right now. If that means
labbing up some silly scenarios maybe someone can share a template of
what i should be labbing up?
How did you really learn redistribution.
Regards,
Nate
