Title : IP Fast Reroute using tunnels
Author(s) : S. Bryant, et al.
Filename : draft-bryant-ipfrr-tunnels-03.txt
Pages : 29
Date : 2007-11-16
This draft describes an IP fast re-route mechanism that provides
backup connectivity in the event of a link or router failure. In the
absence of single points of failure and asymmetric costs, the
mechanism provides complete protection against any single failure.
If perfect repair is not possible, the identity of all the
unprotected links and routers is known in advance.
This IP Fast Reroute advanced method was invented in 2002 and draft
(draft-bryant-ipfrr-tunnels-00.txt) describing it was submitted to
the IETF in May 2004. It was one of the first methods of achieving
full repair coverage in an IP Network, and as such the draft has been
widely referenced in the academic literature.
The authors DO NOT propose that this IPFRR method be implemented
since better IPFRR advanced method capable of achieving full repair
coverage have subsequently been invented.

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
