   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 (Segment ID) 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.
