Hmmm, getting the whole table and becoming transit are definitely not
linked.
I get several full tables from upstreams but I am certainly not transit for
the upstreams. That is, I get routes from UUNet but I only announce my OWN
routes to the upstreams. I think, even with our OC-12's that UUNet,
Broadwing, et. al would be VERY concerned about me advertising a full table
to them ( and thusly becoming transit )
I like to get at least 3 full tables for that if any one ( or heaven help
me ) 2 links go down I still have "internet" routes and a back up. I also
like to get a couple "customer" routes from other providers (for performance
and to lower my transit costs ( although paid peering isn't drastically
cheaper these days )
As far as why you would want to become transit, I am not sure that happens
as much these days. In the days of the traditional NAPS/MAEs it was more
likely but with the proliferation of IX's there just isn't that strong a
case for it.
I hope I am understanding your question correctly.
HTH,
Jim

I will definitely read the book. But just wondering under what
circumstances would want to get the whole routing table or become transit
AS. Thanks

You do not have to become an IP transit. You choose what routes you receive
from and advertise to the other AS's.
