Re: [Idr] Re: draft-ietf-idr-as-pathlimit-03.txt

Hi Tony,

A query on the following language in the draft:

    If the AS_PATHLIMIT attribute is attached to a prefix by a private
    AS, then when the prefix is advertised outside of the parent AS, the
    AS number contained in the AS_PATHLIMIT attribute should be replaced
    by the AS number of the parent AS.

Could it be made more explicit here as to which speaker is 
responsible here?

E.g. is it the responsibility of /all/ pathlimit capable speakers to 
update a private-AS in a pathlimit with a public one (the attribute 
may transit one or more non-pathlimit capable ASes while containing a 
private AS)?

Should a speaker with a private AS, implementing this attribute, be 
pro-active and, when sending an UPDATE to a non-private-AS, set the 
pathlimit AS in such an UPDATE to the peer's ASN?
