valley free routing?

[William Herrin <bill () herrin us>]

Hi folks,

Can anyone tell me about a situation in which a route which was not
valley free was not a result of a misconfiguration or a bad actor? For
those who don't recall the terminology, a network path is valley free
if it crosses exactly zero or one free peering links when traveling
between the two endpoints.

Thanks,
Bill Herrin
