...as well as rfc2260.

to be more specific, we have to note that two different options
are considered there. if you use the first one (read rfc),
then you cannot use private asn until you're ok with
generating inconsistencies (and it seems from the previous
discussions of this topic that this becomes (illegal? ->
no answer...) practice for some smaller isps).

with the second option of 2260, you can use private asn
since the more specific pa routes are always aggregated
(and you cannot use confederations, btw).

after all, as was noted, remove-private-as on cisco can be
replaced by a simple route map, and the attribute manipulation
functionality should definitely exist on versalars...
