O Hai!

I would highly advise you have a read at any presentation by Phil Smith:
ftp://ftp-eng.cisco.com/pfs/seminars (anonymous login)
Read as much as you can from here 1st thing 1st - this is all solid  
ground knowledge.

Then, give a quick read at Cisco's BGP Case Study online on the CCO.
And you're OK to go.

Now if you want paper material that you can keep, I'd suggest  
"Internet Routing Architectures" by Sam Halabi - Cisco Press, even  
though it's getting old, I find it still very valid. Make sure you  
have a read at team-cymru.org before you roll out your  AS, for their  
BOGONs/Martians ACLs and peerings, as it sure helps.

Bear in mind BGP is a simplistic protocol. The pain point *will* be  
your IGP (if you want to do it correctly from start...)
