request for help w/ ATT and terminology

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.

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.

Hi.  I'm by no means an ip/networking expert, and we're having some
difficulty communicating with the boffins at AT&T.  Any
input/advice/translation would be appreciated.

We own our own class C netblock.  Our previous provider, Sprint, had no
problem "adding" it to their network/advertising it (that circuit is now
disconnected).  We've started using an AT&T colo facility, and we're
having a lot of trouble trying to get AT&T to do the same thing there
that Sprint was able to do for us.  AT&T is refusing to advertise our
netblock/path it to our cabinet unless we have an AS number.  ARIN has
refused to give us one on the grounds (rightly so) that we're not
multi-homed.   AT&T says they'll give  us a temporary ASN, and want us
to do eBGP for our netblock.  They sent the technical information over
today, and they want two distinct routers to act as the bgp peers...

Anyway, it's all getting (for us) pretty complicated.   We're a fairly
small firm and just want an Ethernet handoff with our IP block on it.
Sprint didn't blink at the request, but AT&T...  We're getting a good
rate from AT&T for the IP services because it's at their colo.
Switching back to Sprint would definitely be more costly.

Questions:

1.  Is what we're asking for unusual/uncalled for?
2.  What's the technical terminology for the request for AT&T to simply
start advertising our netblock called?  I'm wondering if they're not
understanding our request.

Any other comments/input/suggestions welcomed.

Thanks in advance,

Mike Donahue
