but if you are not paying me, what reasons are there for me to spend my resources (route bloat) so you can engineer your traffic? none.
well, we agree so far :-)
Now tell me how to promulgate my TE-triggering routing advertisements precisely to the edge of my payment boundary (i.e. my upstreams, and their upstreams, and so on recursively along the upstream relationships) and no further, using today's BGP?
but why should i pay the costs because the tool was not designed to do what you want done? i will happily work on tool design with you [0]. but, in the meantime, why should i have to pay a penalty for your odd business choices? ( casual readers should note that 'you' and 'i' are abstract terms, and that geoff usually claims to be more of a capitalist than i :-) randy --- [0] - community-minded folk might suggest that a universally agreed DO-NOT-EXPORT-TO-PEERS community would get you a good way there. at least it would approximately follow the money. also note that filtering peers' announcements on rir allocation boundaries would seem to go a way toward meeting both your needs and mine. and it is what smb's nanog presentation alludes to.
