RE: request for help w/ ATT and terminology
If you want connectivity from both AT&T and Sprint with your one block, you have plenty of justification from ARIN to get your AS assigned assuming both feeds come into one location. However, it looks like you are asking two providers to announce the same block at two different locations (different origin AS on each). If this is the case, it won't happen, you'd be better off justifying an allocation of the additional space from AT&T. -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of Mike Donahue Sent: Wednesday, January 16, 2008 13:37 To: nanog@merit.edu Subject: request for help w/ ATT and terminology Hi.

1) It can, has, and continues to happen all the time. It's a perfectly valid way to route on the Internet. Although not what I would do personally. 2) He said he killed the Sprint line. He also said ARIN (correctly) denied him an ASN because he was not multi-homed. -- TTFN, patrick

He's asking why AT&T can't do the same thing Sprint was doing, as they've disconnected Sprint and are using AT&T alone. My answer: no reason they can't, beyond not wanting to or being really dumb about it. Tell them you want them to advertise your netblock for you because you don't need BGP. You don't have to; they can easily do the routing and announcement for you. If they don't get it easily... well, I'd go back to Sprint, because you'll probably have severe problems later when someone updates something, breaks it and you're down for a week before you can get through to anyone who will listen to your unsupported (to them) setup. I was in the same situation years ago with an Eschelon/ATG circuit: they simply didn't get how to work BGP with a multihomed customer. I could convince them to fix it each time, but then it'd break 4 months later. After the 4th time they screwed up, I dumped them and gladly paid more for anyone else so it would actually work. ~Seth
His Sprint circuit has been disconnected and he only has the AT&T circuit, which comes into his cabinet, inside of AT&Ts Colo facility. AT&T does not want to announce the space without doing an eBGP peer with you because they do not "own" the space. This is their policy, Sprint might not have the same policy. -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of Darryl Dunkin Sent: Wednesday, January 16, 2008 3:55 PM To: Mike Donahue; nanog@merit.edu Subject: RE: request for help w/ ATT and terminology If you want connectivity from both AT&T and Sprint with your one block, you have plenty of justification from ARIN to get your AS assigned assuming both feeds come into one location.
