Each vendor does have multiple methods of practicing this stuff!
As Petr previously mentioned, the best case is to not have routes come back
into the protocol they started in. But it's up to you to figure out how.
Take any lab, and play with multiple ways.
No matter who's products you use, there's no reason you can't take a lab
that offers redistribution and spend extra time playing around with multiple
ways. Just because a vendor (any of them) solves the problem one way, does
not make that the only way to solve it.
I know many people who love to use prefix-lists as their method.
Personally, I prefer tags. But we still need to be aware of what every
device is thinking and seeing at each step. Be liberal with your use of
show commands and/or "debug ip routing" so you get a feel for what goes on
based on commands you entered.
There is no substitution for playing around and seeing it for yourself!
Know what the router is thinking and there's nothing you can't solve!

Actually,
Do a Search of Groupstudy and look for posts by Andrew Caslow aka Bruce
Caslow.
When it comes to redistribution, Bruce is the man!
Others help adding some clarification to the subject, Bruce wrote a nice
piece for GS earlier this year.
Petr from Internetwork Expert wrote a nice paper as well.
The Brians have some interesting techniques.
All come down to the same thing, understanding the administrative distance /
metrics and knowing exactly what you wish to accomplish.
Higher AD to Lower AD, etc.
RIP to OSPF being a classical example.
The Brians 4-Hour Lab Series has a lot of great examples as well.
So there is quite a lot in terms of resources availble and the horse has
been beat to death on Groupstudy.
:)
Practice is really king.
