I have one simple question: as for AS relationship, should customer tell its provider the AS# of its own customers, or the provider have the right to require its customers to do that?
Um... you DO tell your provider the AS numbers of your customers... in the BGP route announcement you send them. It's not a question of rights or requirements. You already do it. Because that's how the technology works. As Chris noted, telling your provider out-of-band before sending the same information via BGP is also a very good idea which enhances the security of the whole doggone Internet.
