I'll just let BGP do its job. > Privately: Hell yes. I'm not a router guy (routing atleast), but perhaps there are performance problems inside an ASN along a path which you connect to other places? So you might lengthen paths through/to that ASN to force traffic across another ASN's direct connection which is less problematic? Or, you just don't want to send traffic through Bill Manning's ASN because you dislike his hawiian T-Shirt Policy? There are probably a few hundred reasosn why you'd avoid an ASN... In general though I'd think that like Michel said: "It's a pain and its doing something that bgp should do for you without lots of messing about"
