Title : Definition of an RRO node-id subobject
Author(s) : J. Vasseur
Filename : draft-ietf-mpls-nodeid-subobject-02.txt
Pages : 9
Date : 2004-2-2
In the context of MPLS TE Fast Reroute, the Merge Point (MP) address is
required at the Point of Local Repair (PLR) in order to select a backup
tunnel intersecting a fast reroutable Traffic Engineering LSP on a
downstream LSR. However, existing protocol mechanisms are not
sufficient to find an MP address in multi-areas or multi-domain routing
networks. Hence, the current MPLS Fast Reroute mechanism cannot be used
to protect inter-area or inter-AS TE LSPs from a failure of an ABR
(Area Border Router) or ASBR (Autonomous System Border Router)
respectively. This document specifies the use of existing RRO IPv4 and
IPv6 subobjects (with a new flag defined) to define the node-id
subobject in order to solve this issue. Note that the MPLS Fast reroute
mechanism mentioned in this document refers to the 'Facility backup'
MPLS TE Fast Reroute method.

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.
