I believe this to be the case. A caution, however: RFC 1771 has
quite a few errors and does not, in many cases, reflect actual
implementation practice. I strongly recommend using
http://www.ietf.org/internet-drafts/draft-ietf-idr-bgp4-24.txt as the
reference, which is likely to become RFC Any Day Now (which I've been
saying since around draft 20). Actually, the RFC status does seem
close, as the IDR Working Group is now going through the
Implementation Report and other hoops required to get a Standards
Track RFC approved.
