Operational Management of Loop-Free Alternates
RFC 7916, “Operational Management of Loop-Free Alternates”, is a Proposed Standard document published in July 2016 by S. Litkowski, B. Decraene, C. Filsfils, K. Raza, M. Horneffer, P. Sarkar. The canonical text is published by the RFC Editor.
Abstract
Loop-Free Alternates (LFAs), as defined in RFC 5286, constitute an IP Fast Reroute (IP FRR) mechanism enabling traffic protection for IP traffic (and, by extension, MPLS LDP traffic). Following early deployment experiences, this document provides operational feedback on LFAs, highlights some limitations, and proposes a set of refinements to address those limitations. It also proposes required management specifications.
This proposal is also applicable to remote-LFA solutions.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
