We had a similar problem with Sprint. We have a 10Mbit circuit to
Verizon and a T1 backup from Sprint. For the Sprint customers, they had
it set for their connection to us to be the preferred path regardless of
what we were announcing. I had to get them to change their routing
policy for our address space so that this wouldn't occur. We had no way
of changing it since all of the weights we could have applied would only
work if both of the connections were terminating into the same router.
The local-preference is router specific. If we would have been
terminating both ISP circuits to the same router, we would have been
able to control the preferred path from our router. Since this wasn't
the case, I had to have Sprint change their end.
HTH,

Not sure if this will help.
<We have one connection (DS-3) to AT&T and one conncetion (DS-3) to SBC
for internet access. We have BGP in place and prefer all traffic to go
through AT&T.
- Can't you configure BGP to take preference of ATT over SBC? <Here's
the problem, local DSL subscribers are on the SBC network, so all of
our home workers with DSL go take the SBC route instead of the AT&T.
I can understand that because it's the local network that it's the
preferred route, but can I chnage it to route through AT&T or would all
that be internal to SBC's network?
- Are the home workers using VPN to get into your network, and if they
are,
can't you use a public ip from ATT?
Regards,
John
