I have to provide services to stub routers, but cannot trust them to act entirely benevolently, because I don't own, operate or even have much influence over what brand they are. I want to provide a the best and possibly better service to them because their owners are paying me to e.g., local layer 2 switching in the exchange, but I cannot let one customer impact the service of any other customer.
