Local protection reroutes the traffic rapidly around the failure, so this mechanism is called “Fast Reroute (FRR)”. In local protection the aim is not using another path

This document provides a framework for the development of IP fast- reroute mechanisms that provide protection against link or router failure by invoking locally determined repair paths. Unlike MPLS fast-reroute, the mechanisms are applicable to a network employing conventional IP routing and forwarding.

When you enablefast reroute, detours are precomputed and preestablished along theLSP. In case of a network failure on the current LSP path, trafficis quickly routed to one of the detours.

For these reasons, Fast ReRoute (FRR) has been developed. FRR is a technology, that minimizes network repair time after a link or node failure, mainly in the ISP networks. Fast reroute (FRR) mechanisms are widely used in IP and MPLS networks by computing the recovery path before a failure occurs. The centralized control plane in SDN can potentially enhance path Another frequently asked question regarding Link Protection and Fast Reroute is why are they needed, or what is the benefit of having then enabled, when an LSP is already configured with a primary path and a secondary path, AND the standby option is set. RFC 4090 RSVP-TE Fast Reroute May 2005 When a failure occurs along the protected LSP, the PLR redirects traffic onto the local detour.


There have been considerable efforts using FRR towards minimizing rerouting time in traditional IP and MPLS networks [12]–[15].
