MPLS fast reroute [3] is considered as a possible solution to protect
traffic against link and node failures by re-directing the traffic
locally to a backup LSP. A backup LSP can be either a detour LSP or a
bypass tunnel. This document describes two methods to optimize the
routing of detour LSPs such that they merge faster, a distributed
method and a centralized method. The distributed method uses the
Backup Record Route Object (BRRO) and the centralized method uses the
Backup Explicit Route Object (BERO). The latter can also be used for
bypass tunnels.

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
