CIDRadvisor requires aut-num's to be populated to figure out differing as paths. Given the state of aut-num's in IRR, it is not a very useful tool. One could use as paths from a BGP route table dump. But that is only an estimate, as two routes flap the as paths may diverge differently. > > randy Cengiz -- Cengiz Alaettinoglu Information Sciences Institute http://www.isi.edu/~cengiz University of Southern California
