Loop-Free Alternate Applicability in Service Provider Networks
RFC 6571, “Loop-Free Alternate Applicability in Service Provider Networks”, is an Informational document published in June 2012 by C. Filsfils, P. Francois, M. Shand, B. Decraene, J. Uttaro, N. Leymann, M. Horneffer. The canonical text is published by the RFC Editor.
Abstract
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 an Internet Standards Track specification; it is published for informational purposes.
