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.

Item Type: Standardization Contributions
Additional Information: LFA Applicability: Pierre Francois was the editor of RFC 6571 [2], "LFA applicability in SP networks", co-edited with Clarence Filsfils, distinguished engineer at Cisco Systems. This RFC presents an analysis of the applicability of an IP Fast Reroute technique called "Loop-free alternates" in Internet Service Provider Networks. This work has been performed in collaboration with Cisco Systems, France Telecom - Orange, AT&T, and Deutsche Telekom.
