I'm trying to understand the problem being solved by the Cisco
private AS removal feature. In particular, what advantages does it
offer over confederations, which would seem to do the same thing when
externally advertising customer routes? Is there a performance
benefit?
RFC1998-style multihoming with a private AS is a possible
application, I suppose, for any routes that are NOT marked with
NO-EXPORT.
