Well looks like that have more BOGON problems. They are sending 128.161.0.0/3. These guys love claiming default gateway traffic? At 07:00 PM 11/24/2003, william@elan.net wrote:

Keep in mind both that there is no normalized view presented to route-views (0/0 is seen at times) and that looking at only one POV will always bite you. None of those paths are visible from 3303 directly, nor are visible in a quick survey of a small handful or live-table BGP views. While the as-path is interesting and doesn't directly correspond to a n obvious relationship, this looks more like some entity in the path or at 3277 either representing 0/0 or [more likely] taking a bogon feed and regurgitating it. -- RSUC / GweepNet / Spunk / FnB / Usenix / SAGE
