OSPF Two-Part Metric
RFC 8042, “OSPF Two-Part Metric”, is a Proposed Standard document published in December 2016 by Z. Zhang, L. Wang, A. Lindem. It updates RFC 2328. The canonical text is published by the RFC Editor.
Abstract
This document specifies an optional OSPF protocol extension to represent router metrics in a multi-access network in two parts: the metric from the router to the network and the metric from the network to the router. For such networks, the router-to-router metric for OSPF route computation is the sum of the two parts. This document updates RFC 2328.
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.
