What you're calling context, I call deceptive. For one thing, Centurylink's process is, like a spammer, opt-out rather than opt-in. 3356 enables the local pref unless told through a BGP community not to. There's no evidence that 47787 even knows that Centurylink is preferring them despite shorter AS paths elsewhere, let alone desires that behavior. Indeed, given the prepends that 47787 added, it's quite possible they desire the opposite. For another, a key implication in your "context" is that if one customer intentionally pays 3356 to intentionally send another customer's packets on a longer, slower trip than 3356 otherwise would, that's a legitimate above-board business transaction. Not obviously corrupt. Regards, Bill Herrin -- William Herrin bill () herrin us https://bill.herrin.us/
