Impact of Shortest Path First Trigger and Delay Strategies on IGP Micro-loops
RFC 8541, “Impact of Shortest Path First Trigger and Delay Strategies on IGP Micro-loops”, is an Informational document published in March 2019 by S. Litkowski, B. Decraene, M. Horneffer. The canonical text is published by the RFC Editor.
Abstract
A micro-loop is a packet-forwarding loop that may occur transiently among two or more routers in a hop-by-hop packet-forwarding paradigm.
This document analyzes the impact of using different link state IGP implementations in a single network with respect to micro-loops. The analysis is focused on the Shortest Path First (SPF) delay algorithm but also mentions the impact of SPF trigger strategies.
