Application of the Border Gateway Protocol in the Internet

Status of this Memo

This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.

Abstract

This document, together with its companion document, "A Border Gateway Protocol 4 (BGP-4)", define an inter-autonomous system routing protocol for the Internet. "A Border Gateway Protocol 4 (BGP-4)" defines the BGP protocol specification, and this document describes the usage of the BGP in the Internet.

Information about the progress of BGP can be monitored and/or reported on the BGP mailing list (bgp@ans.net).

This document was originally published as RFC 1164 in June 1990, jointly authored by Jeffrey C. Honig (Cornell University), Dave Katz (MERIT), Matt Mathis (PSC), Yakov Rekhter (IBM), and Jessica Yu (MERIT).

The following also made key contributions to RFC 1164 -- Guy Almes (ANS, then at Rice University), Kirk Lougheed (cisco Systems), Hans- Werner Braun (SDSC, then at MERIT), and Sue Hares (MERIT).

We like to explicitly thank Bob Braden (ISI) for the review of the previous version of this document.

This updated version of the document is the product of the IETF BGP Working Group with Phill Gross (MCI) and Yakov Rekhter (IBM) as editors.

John Moy (Proteon) contributed Section 7 "Required set of supported routing policies".

Scott Brim (Cornell University) contributed the basis for Section 8 "Interaction with other exterior routing protocols".

Most of the text in Section 9 was contributed by Gerry Meyer (Spider).

Parts of the Introduction were taken almost verbatim from [3].

We would like to acknowledge Dan Long (NEARNET) and Tony Li (cisco Systems) for their review and comments on the current version of the document.
