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


2. Introduction.

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 [1].

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

3. Acknowledgements.

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.

4. Documentation.

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 [3]. The

changes between versions 1, 2 and 3 are explained in Appendix 3 of

[3]. 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...
