    abstract =  {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 SID stack can be supported in a given network. This document only defines one type of MSD (Base MPLS Imposition), but defines an encoding that can support other MSD types. This document focuses on MSD use in a Segment Routing enabled network, but MSD may also be useful when Segment Routing is not enabled.},
