Re: OT: Building Scalable Data Centers: BGP is the Better IGP

more info on design could be found here (only L3 aspects are covered,
there is a LOT of important things at physical layer too):

http://tools.ietf.org/html/draft-lapukhov-bgp-routing-large-dc-03

Scale is irrelevant, main limiting factors would be application
requirements, e.g. with regards to load-balancing. We do not implement
mobility solutions that require L2 domain stretching, but it's
possible to do this (though not recommended) over the L3 network.

Network management/config automation is integrated into AutoPilot

Which is much more than configuration management system - rather an
engine for complete data-center life-cycle management.
