Title : Basic Specification for IP Fast-Reroute: Loop-free

This document defines an architecture and selection process for
providing local protection for IP unicast and/or LDP traffic in the
event of a single link or node failure until the router has
converged. When computing the primary next-hop for a prefix, a
router S also determines an alternate next-hop which can be used if
the primary next-hop fails. The alternate next-hop is said to be a
loop-free alternate, which goes to a neighbor whose shortest path to
the prefix does not go back through the router S.

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.
