I still fail to understand. If I am correct, AS3908 and AS209 are somehow related in that Qwest was required to sell off all long haul circuits that go into the former USWest territory. I wasn't aware that this impacted the Qwest IP backbone as well, however this has been brought to my attention. What I don't understand is why AS3908 can't aggregate before advertising to C&W, which then goes into AS209.

If for whatever reason qwest feels the need to leak their /30's and /32's to bbn, it could at least be no-export. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6)
