All:
Thanks for the replies off-list. Telocity (AS12050) got a hold of me and the problem is now solved. Thanks!

Subject: BGP Question: Problems with connectivity when using local
preferences
All:
We are running BGP4 between Sprint and UUNet. We are using route-maps to add local preferences to certain AS numbers to force traffic out Sprint rather than UUNet. One of the AS's we force out Sprint is AS3356 (Level3).
Our CTO has a DSL line from a local provider. When he traceroutes from his DSL connection, he goes across the DSL provider, Level3, and stops at UUNet. When I run a traceroute to his DSL IP, I go across UUNet, Level3, and stop at the DSL provider's router.
Here is the AS path that my traceroute takes: AS701 -> AS3356 -> AS12050
Here is the AS path that his traceroute takes: AS12050 -> AS3356 -> AS701
We are forcing Level3 routes out our Sprint connection, but AS12050 routes go out UUNet (no local-preference change).
When I took out Level3's AS from our route-map, thus sending Level3 routes out UUNet, everything worked fine. He could reach us and I could him. Any ideas why?
