Yes, the BGP message had a transitive attribute - sorry if I was not clear.
That said, you may want to ask why you are getting RIS routes if you are not peering with them directly :p

RIS is peering world wide ( http://www.ripe.net/ris/docs/peering.html ) but the mail was only sent to linx-ops and tech-l, so the announcement may have been limited to europe (for all I know).
