This would be for a large enterprise network in a multiple hub spoke configuration. I want use Private BGP AS's internally and would be completely separate from the Ebgp connections to my Transit providers. I was thinking EBGP in my core so I could use all the different BGP features such as loc-pref, meds etc and also not have to worry about full-meshing IBGP or route-reflectors. Ill check out the nanog article thanks

Depends on the definition of enterprise I suppose.. If you want to build the
backbone level with similarity to a service provider backbone (for example a
large enterprise network backbone), then go to www.nanog.org and in the previous
nanog meetings, Philip Smith from Cisco has some excellent presentations about
SP BGP configuration with a few sample configs and a case study.
IMHO, I'd use IBGP at the core. Run EBGP with upstreams, and any downstream
sites requiring bgp hookup to the backbone.
