Title : P2MP MPLS-TE Fast Reroute with P2MP Bypass Tunnels
Author(s) : J. Le Roux
Filename : draft-ietf-mpls-p2mp-te-bypass-02.txt
Pages : 14
Date : 2008-2-27
This document defines procedures for fast reroute protection of
Point-To-MultiPoint (P2MP) Traffic Engineering Label Switched Paths
(TE-LSP) in MultiProtocol Label Switching (MPLS) networks, based
upon Point-To-MultiPoint Bypass Tunnels. The motivation for using
P2MP Bypass Tunnels is to avoid potentially expensive data
duplication along the backup path that could occur if Point-To-Point
Bypass Tunnels were used, i.e., to optimize the bandwidth usage,
during fast reroute protection of a link or a node. During link or
node failure the traffic carried onto a protected P2MP TE-LSP is
tunnelled within one or several P2MP Bypass Tunnels towards a set of
Merge Points. To avoid data duplication, backup labels (i.e., inner
labels) are assigned by the Point of Local Repair (PLR) according to
the RSVP-TE upstream label assignment procedure.

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