Signaling Maximum SID Depth Using OSPF
RFC 8476, “Signaling Maximum SID Depth Using OSPF”, is a Proposed Standard document published in December 2018 by J. Tantsura, U. Chunduri, S. Aldrin, P. Psenak. The canonical text is published by the RFC Editor.
Abstract
This document defines a way for an Open Shortest Path First (OSPF) router to advertise multiple types of supported Maximum SID Depths (MSDs) at node and/or link granularity. Such advertisements allow entities (e.g., centralized controllers) to determine whether a particular Segment Identifier (SID) stack can be supported in a given network. This document only refers to the Signaling MSD as defined in RFC 8491, but it defines an encoding that can support other MSD types. Here, the term "OSPF" means both OSPFv2 and OSPFv3.
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.
