Signaling Maximum SID Depth (MSD) Using the Border Gateway Protocol - Link State
BGP-LS
SID
MSD
SR
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 entities (e.g., centralized controllers) to
determine whether a particular Segment Identifier (SID) stack can be
supported in a given network.
