Communities. Ask sprint (or look in the IRR) about the communities they have configured in their announcements. At least they probably have *backbone -- their own network *customers *peers a transit customer, such as you, would get all 3. A peer would get the 1st two. You configure the local-pref for the sprint customer community to go to sprint. Ditto for BBN if you have their service. On Mon, 19 Jun 2000, Peter Francis wrote:
My mistake in the original post. I am looking for the list of (for instance) customers of Sprint that are purely "downstream" of Sprint. Now that I think about there may not be any easy way to distinguish between a small ISP that is multi-homed to Sprint and some other provider (their traffic I would want to send to Sprint) and BBN (who also appear to be one AS hop behind Sprint from my networks perspective and whose traffic I do not want to send to Sprint.) I know I can come up with a list of "major" backbone AS's and filter their traffic off by hand but I was looking for a "cleaner" solution by using the IRR. I hope that clarifies what I am trying to accomplish.

If they are non-transit customers, then their networks won't be announced outside of that provider's own network. So unless you can access that provider's own BGP tables directly you can't know this information. -- Joe Rhett Chief Technology Officer JRhett () ISite Net ISite Services, Inc.
