Redistribution is one of those areas that's more an art than science in my
opinion. No single solution fits all situations so successful
redistribution is more driven by logic and philosophy rather than the actual
mechanicals to make it work. Start digging into the details of
redistribution and what takes place "under the hood" so to speak. Once you
understand the logical side the mechanicals are just a minor detail.
One other thing...the NMC guy is Bruce Caslow, one of many CCIE legends who
have hung around this list at one time or another and possibly the VERY best
at complex redistribution methodology. ;-)

The explanations in the IE blog are really good, thanks for providing these
links!
Does anyone has other great ressources or can tell the own strategy?
thanks

IE blogs have some entries about this topic (links below). Also, a guy from
NMC posted few long good emails to this list before. Do google, and also
check their website.

Hi Group,
As some others already mentioned, I do also need too much time on
redistribution.
Can you experts out there give some strategies how to nail these problems
down? Lets think about a complex scenario with many routing protocols and
some special task's like for example:"The link over EIGRP should be prefered
but if the link goes down you still need full connectivity and so on...make
sure that you have full IP connectivity
How do you start? Do you draw everything into your diagram before you start?
What's the (logical) method you set the tags, communities...Do you take care
about the "best path", preventing subobtimal routing (if nothing is
specially asked in the task)?
And at least, how do you verify it, that you can be 100% sure?
Are there any good documents about the strategies? Somehow the Doyle book
does not give me what I'm looking for.
I really hope you guys have good ideas - strategies, this would really help
me, and I guess, many others.
Thanks a lot
Roger
