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 LSRs. 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. Two mechanisms are defined
that also provide integrity protection of the information carried
within LDP messages and protect against the malicious replay of LDP
messages. Both proposed mechanisms require ordered control LDP and
can also be applied to CR-LDP.

NOTE:	The mail server at ietf.org can return the document in

	exhibit different behavior, especially when dealing with
