It's a fine line between why and how.
I'm counting days down to my lab, and everything has become how.
I agree understanding why a single point of redistribution is much
easier to manage is important. But faced with the fact they ain't going
to give you single point of redistribution, assuming every
redistribution is multiple protocols over multiple routers may save you
both study time and lab time.
All the rules and techniques that apply the multiple point also apply to
single point redistribution.
Another thing I would pass on, is to be Highly Suspect of any /32 bit
routes. I've never had a /32 bit route that was at the right place at
the right time for the right reason. I've had plenty of /32 routes at
the wrong place for the wrong reason, at the wrong time.
My strategy is to kill them on sight during redistribution, which is
easy to do with route maps. Now, the auto-grading in the Lab may have a
problem with this, but I don't care. 32 bit routes are the root of all
redistribution evil from my view point.
Truly, any route smaller than your interface ip address statements can
and will cause problems.
That's my how, and I'm sticking to it.
Michael

i agree on your point and it is my strategy as well ..however it is
better to understand why we do things ...the question is why it is
really needed (where some of the books they said for single point of
redistrubtions ..you dont have to worry about filters ) ...if i dont
have to worry then i can also save time ..right ?
