Anyone,
Hopefully this is a simple question about RADB. I'm supporting a small wireless ISP, they just recently added a second upstream connection - Charter (AS 20115). The IP space was originally issued by the other upstream Windstream (AS 7029). Looking at a few resources such as the bgp.he.net to see who peers with who and looking glasses, it seems that not all of AS 20115 peers are accepting our prefix. AT&T is an example - AS7018. In one case, it's an upstream 2 levels up - Century Link accepts from Charter, but Level 3 doesn't accept it from Century Link. Charter uses RADB. The entry for the prefix looks like this:
What makes you think Level3 is not accepting from CenturyLink? I suspect Century Link may be a peer of Level3 instead of a customer. Windstream appears to be a customer of Level3. Level3 will put a higher local pref on customer routes. Courtney Smith courtneysmith@comcast.net () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments
