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.
Isn't that the way most of the IPv6 internet ran for many years? ISP A -> 6939 <- ISP B, settlement-free connections all around? It's what established 6939 as the core of the IPv6 internet. Matt
Thanks, Bill Herrin
