       Application of the Border Gateway Protocol in the Internet

Status of this Memo

   This RFC, together with its companion RFC-1163, "A Border Gateway
   Protocol (BGP)", define a Proposed Standard for an inter-autonomous
   system routing protocol for the Internet.

   This protocol, like any other at this initial stage, may undergo
   modifications before reaching full Internet Standard status as a
   result of deployment experience.  Implementers are encouraged to
   track the progress of this or any protocol as it moves through the
   standardization process, and to report their own experience with the
   protocol.

   This protocol is being considered by the Interconnectivity Working
   Group (IWG) of the Internet Engineering Task Force (IETF).
   Information about the progress of BGP can be monitored and/or
   reported on the IWG mailing list ().

   Please refer to the latest edition of the "IAB Official Protocol
   Standards" RFC for current information on the state and status of
   standard Internet protocols.

   Distribution of this memo is unlimited.
