Theories include: - trying to make a /20 announcement more important than a component /24 by prepending the /24 out of sight (i'm not joking, some people really believe this!!) - trying to over-ride policy that their upstream provider has applied (e.g. my prepended /20 is a backup to my main /20 announcement but my upstream on the backup path is local pref-ing high to make them look more "peerable") There are bound to be other reasons... :-) philip --
