An Architecture for IP/LDP Fast Reroute Using Maximally Redundant Trees
Overview
RFC 7812, “An Architecture for IP/LDP Fast Reroute Using Maximally Redundant Trees”, is a Proposed Standard document published in June 2016 by A. Atlas, C. Bowers, G. Enyedi. The canonical text is published by the RFC Editor.
Abstract
This document defines the architecture for IP and LDP Fast Reroute using Maximally Redundant Trees (MRT-FRR). MRT-FRR is a technology that gives link-protection and node-protection with 100% coverage in any network topology that is still connected after the failure.
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.
