Experience with the BGP Protocol
1. Status of this Memo.
This memo provides information for the Internet community. It does
not specify an Internet standard. Distribution of this memo is
The purpose of this memo is to document how the requirements for
advancing a routing protocol to Draft Standard have been satisfied by
Border Gateway Protocol (BGP). This report documents experience with
BGP. This is the second of two reports on the BGP protocol. As
required by the Internet Activities Board (IAB) and the Internet
Engineering Steering Group (IESG), the first report will present a
performance analysis of the BGP protocol.
The remaining sections of this memo document how BGP satisfies
General Requirements specified in Section 3.0, as well as
Requirements for Draft Standard specified in Section 5.0 of the
"Internet Routing Protocol Standardization Criteria" document .
This report is based on the work of Dennis Ferguson (University of
Toronto), Susan Hares (MERIT/NSFNET), and Jessica Yu (MERIT/NSFNET).
Details of their work were presented at the Twentieth IETF meeting
(March 11-15, 1991, St. Louis) and are available from the IETF

The BGP protocol has been developed by the IWG/BGP Working Group of
the Internet Engineering Task Force. We would like to express our
deepest thanks to Guy Almes (Rice University) who was the previous
chairman of the IWG Working Group. We also like to explicitly thank
Bob Hinden (BBN) for the review of this document as well as his
constructive and valuable comments.
BGP is an inter-autonomous system routing protocol designed for the
TCP/IP internets. Version 1 of the BGP protocol was published in RFC
1105. Since then BGP Versions 2 and 3 have been developed. Version 2
was documented in RFC 1163. Version 3 is documented in . The
changes between versions 1, 2 and 3 are explained in Appendix 3 of
. Most of the functionality that was present in the Version 1 is
present in the Version 2 and 3. Changes between Version 1 and
Version 2 affect mostly the format of the BGP messages. Changes
between Version 2 and Version 3 are quite minor.
BGP Version 2 removed from the protocol the concept of "up", "down",
and "horizontal" relations between autonomous systems th...
