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 : LSP Hierarchy with MPLS TE
Author(s) : K. Kompella, Y. Rekhter
Filename : draft-ietf-mpls-lsp-hierarchy-01.txt
Pages : 11
Date : 25-Sep-00
To improve scalability of MPLS TE it may be useful to aggregate TE
LSPs. The aggregation is accomplished by (a) an LSR creating a TE
LSP, (b) the LSR forming a forwarding adjacency out of that LSP
(advertising this LSP as a link into ISIS/OSPF), (c) allowing other
LSRs to use forwarding adjacencies for their path computation, and
(d) nesting of LSPs originated by other LSRs into that LSP (by using
the label stack construct).
This document describes the mechanisms to accomplish this.

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.
