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.
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 (firstname.lastname@example.org).
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.

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.
This memo describes the use of the Border Gateway Protocol (BGP)  in the Internet environment. BGP is an inter-Autonomous System routing protocol. The network reachability information exchanged via BGP provides sufficient information to detect routing loops and enforce routing decisions based on performance preference and policy constraints as outlined in RFC 1104 . In particular, BGP exchanges routing information containing full AS paths and enforces routing policies based on configuration information.
As the Internet has evolved and grown over in recent years, it has become painfully evident that it is soon to face several serious scaling problems. These include:
- Exhaustion of the class-B network address space. One fundamental cause of t...
