This memo describes a generalized approach for achieving IP fast
restoration in response to link and router failures by using IP
routing to support high network availability.  The approach relies
on the utilization of flat, yet highly-localized routing technology
to reduce far-reaching control message propagation, thereby limiting
the effects of a failure and enabling sub-second restoration.  It
then outlines how the Temporally-Ordered Routing Algorithm (TORA) (a
Mobile Ad hoc Network (MANET) routing protocol), when suitably
modified for use in fixed networks, can be used within this
framework. The general approach to routing topology management
within the fast restoration framework is immediate reaction on link
failure (to preserve existing flows) and gradually integration of
new network elements on activation into the domain (to further
assure stability).
