Signaling Maximum SID Depth (MSD) Using IS-IS
RFC 8491

Received changes through RFC Editor sync (created alias RFC 8491, changed title to 'Signaling Maximum SID Depth (MSD) Using IS-IS', changed abstract to 'This document defines a way for an Intermediate System to Intermediate System (IS-IS) 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 ID (SID) stack can be supported in a given network.  This document only defines one type of MSD: Base MPLS Imposition.  However, it defines an encoding that can support other MSD types.  This document focuses on MSD use in a network that is Segment Routing (SR) enabled, but MSD may also be useful when SR is not enabled.', changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2018-11-14, changed IESG state to RFC Published)
