It appears as either AS# to your peers. e.g. your customer can change the 'remote-as' at their convenience, without needing to synchronize the change with you. You can opt not to prepend, so that you'll always just see your real-AS customer-AS in AS-path, not the 'local-as' even if the customer is actually peering with it. Same goes other way, you can opt so that customer sees prefixes coming just from the AS# they peer with, not the local-as + real-as. e.g. you can do migration, without increasing AS path length to either side at any point. This mostly makes sense, if you have quite large bunch of customers, and only makes sense in migration, same with local-as. I would dearly recommend the original poster to just go ahead and do full migration in rather rapid way to a single AS, I foresee quite bit of headache from the setup otherwise.
