This document defines a way for a Border Gateway Protocol Link-State (BGP-LS) speaker to advertise multiple types of supported Maximum SID Depths (MSDs) at node and/or link granularity. Such advertisements allow logically centralized entities (e.g., centralized controllers) to determine whether a particular SID stack can be supported in a given network.
