In this document, we analyze the applicability of the Loop-Free
Alternate (LFA) method of providing IP fast reroute in both the core
and access parts of Service Provider networks.  We consider both the
link and node failure cases, and provide guidance on the
applicability of LFAs to different network topologies, with special
emphasis on the access parts of the network.  This document is not
