What is the benefit for a customer or a provider in doing this v.s just the customer prepending their own AS?
Prepending done customer side would be visible to anyone beyond that first BGP peering between the customer and provider, including any of the provider's other BGP customers.
Generally, these provider prepend communities would be targeted for external relationships. So, example would be that you want to have provider X's customers send to you directly via provider X, but provider X's peering sucks so you want anyone who is *not* a direct customer of provider X to avoid routing through provider X.
