That sounds like a disreputable practice. While not quite as obvious, some large transit ASes, like Level3, reset the origin to I (best) sometime between when they learn it and when they announce it to their customers and peers. This similarly causes them to suck in a bit more traffic than they might otherwise. -- Jeff S Wheeler <j...@inconcepts.biz> Sr Network Operator / Innovative Network Concepts
