Is there something silly going around? I doubt I'm the only one noticing these being triggered by our generous maxas-limit setting. Oct 9 23:01:46: %BGP-6-ASPATH: ... 27754 27754 27754 ... Oct 17 11:10:40: %BGP-6-ASPATH: ... 43413 43413 43413 ... Oct 22 06:34:09: %BGP-6-ASPATH: ... 38230 38230 38230 ... Anyone have theories as to what these networks are trying to accomplish?
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 --
