Can anyone peering with Level3 directly tell me if they are seeing 63.210.162.0/24 coming from the Level3 peer? Thanks for the help. Cheers, -- Joe Renwick IP Network Consultant, CCIE #16465 GO NETFORWARD! Direct: 619-800-2055, Emergency Support: 800-719-0504 Is your network moving you forward?

Thanks again to all who replied... looks like other Level3 customer are seeing the /24. Looks like the issue is specific to San Diego. Any routing information from other SD Level3 customer would be appreciated. Cheers, Joe On Fri, May 13, 2011 at 1:39 AM, Joe Renwick <joe@gonetforward.com> wrote:

Thanks for all who assisted me on this issue. Was invaluable to get router output from all over the country. Bottom line Level3 had some issues with poking a whole in there summarization filters. Appeared that the problem was only with peers connected to the HSA1 and HSA2 routers in San Diego. That is where our routers are located so looks like a local issue. I did not get a clear answer for them on the root cause but from what I understand they updated their summarization policy but did not clear the BGP sessions. Not sure if anyone else has run into this in the past with Level3. I have worked with them a couple times previously doing the same thing and had no issue.
