After reading through the BGP literature it seems to me that you can use confederations to solve two different BGP design problems 1) To minimize the number of connections between routers. The full mesh rule. Route reflectors does this too. 2) To advertise many ASes to the internet with one legal AS(assigned from IANA or RIPE). This is good when two ISPs merge. Regards Jon Gudmundsson
