Status of this Memo

   This protocol is being developed by the Border Gateway Protocol
   Working Group (BGP) of the Internet Engineering Task Force (IETF).
   This RFC specifies an IAB standards track protocol for the Internet
   community, and requests discussion and suggestions for improvements.

   Standards" 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 (BGP-3)", define an inter-autonomous system routing
   protocol for the Internet.  "A Border Gateway Protocol (BGP-3)"
   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 ().
