A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Multiprotocol Label Switching Working Group of the IETF.
Title : Multi Protocol Label Switching Label Distribution
Protocol Query Message Description
Author(s) : P. Ashwood-Smith, A. Paraschiv
Filename : draft-ietf-mpls-lsp-query-07.txt
Pages : 19
Date : 2003-6-12
This document describes the encoding and procedures for three new
Label Distribution Protocol (LDP) messages: Query Message, Query-
Reply Message and Partial Query-Reply Message. A Label Edge Router
(LER) sends a Query message when it needs to find out information
about an established Label Switched Path (LSP). The Query message
can be used for LDP LSPs as well as for Constraint-Based Label
Switched Paths (CR-LSPs). The queried data is encoded into the
Query-Reply messages.

In the body type:
"FILE /internet-drafts/draft-ietf-mpls-lsp-query-07.txt".
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.
