	Title		: End to end authentication for LDP

The Label Distribution Protocol (LDP), as currently defined, makes
use of the TCP MD5 Signature option to protect (authentication and
integrity) the LDP traffic between two adjacent LSR's. This document
specifies extensions to LDP to enable end-to-end authentication
between non-adjacent LSR's (ie not directly connected via a TCP
connection) that are setting up an LSP. This mechanism also provides
integrity protection of the information carried within LDP messages
and protects against the malicious replay of LDP messages. The
proposed mechanism requires ordered control LDP and can also be
applied to CR-LDP.

In the body type:

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.
