​oh! "hey, cool code kid, got an email to the submission bot to get your
changes to where we can all see them?" (version of: ​

err, maybe nick was thinking there might be more revisions on his text
options?

I'm not a native bgp speaker, but I'd question (for instance) the use of
'AS_PATH segment' in this part of the draft, given:

            "AS_PATH is a well-known mandatory attribute that is composed
            of a sequence of AS path segments.  Each AS path segment is
            represented by a triple <path segment type, path segment
            length, path segment value>."

from: https://tools.ietf.org/html/rfc4271

I would have thought 'segment' was an individual 'asn' (the triple I
suppose, the TLV) in the AS_PATH, not the whole 'AS_PATH' attribute. Maybe
instead of 'AS_PATH segment' in nick's revision:

             "This differs from the behaviour
              specified in section 5.1.2 of <xref target="RFC4271" />, which
              requires that the BGP speaker prepends its own AS number as
              the last element of the AS_PATH.  While it is technically
              possible to operate a route server which prepends its own AS
to
              the AS_PATH, it is not recommended to do so because this
              may adversely affect the resulting network topology between
the
              route server clients."

​again, I'm not a native bgp speaker, so I'm probably off base, but...
maybe there's a revision in the revision still to be had before updating
the actual draft archive?​
