Title : Fast Reroute Extensions to Constraint based Routed
Label Distribution Protocol

This document proposes extensions to existing CR-LDP for setting up
MPLS backup tunnels. These tunnels can protect Label Switched Paths
on an exclusive bandwidth basis or shared bandwidth on the back up
paths, as desired by the initiator of the tunnel at the head end
node. Several backup segments are maintained for a single LSP and
they are meant to provide link and node failure protection along
various segments of the LSP. Sharing of backup segments across
multiple LSPs is also facilitated to achieve scalability

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.
