Technical Summary
This informational document provides a framework for the development
of IP fast-reroute mechanisms which provide protection against link
or router failure by invoking locally determined repair paths.
Unlike MPLS fast-reroute, the mechanisms are applicable to a network
employing conventional IP routing and forwarding.
Working Group Summary
This document is a basis for much of the work that has been ongoing
in the RTGWG working group for several years. No controversy

techniques mentioned in the framework, notably loop-free
alternates (RFC5286).
