It was not without a reason that I proposed to start with agreeing on and writing down definition of these important terms and acronyms: http://www.ietf.org/mail-archive/web/i2rs/current/msg00554.html We have gone through similar discussions in the NETMOD WG regarding the document draft-ietf-netmod-routing-cfg. In short, IETF standards and various vendors (plus their customers) use these terms with different meanings.
