Re: RIPE NCC Region Weekly Routing Report

[Geoff Huston <]

You should not be surprised if you get the answer is "We
accept the routes they send us because as a customer of ours
they pay us money, and in exchange we carry and advertise the
routes they advertise to us".

Of course you should not be surprised if you get no answer
at all, on the basis that the provider may be of the view that
the details of a commercial relationship with a customer are
not part of the public domain.

Its a tricky problem, and the lack of forcing functions in the
routing space is part of the particular characterization of this
space.
