IESG Note:
 
   This document describes currrent existing practice for securing BGP
   against certain simple attacks.  It is understood to have security
   weaknesses against concerted attacks.

Note: This revision reflects comments received during the last call period.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Inter-Domain Routing Working Group of the IETF.

	Title		: Protection of BGP Sessions via the 
                          TCP MD5 Signature Option
	Author(s)	: A. Heffernan

   This memo describes a TCP extension to enhance security for BGP.  It
   defines a new TCP option for carrying an MD5 [RFC1321] digest in a
   TCP segment.  This digest acts like a signature for that segment,
   incorporating information known only to the connection end points.
   Since BGP uses TCP as its transport, using this option in the way
   described in this paper significantly reduces the danger from certain
   security attacks on BGP.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
