This document defines a way for an Open Shortest Path First (OSPF)
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 Identifier (SID) stack can be supported in a given
network. This document only refers to the Signaling MSD as defined
in RFC 8491, but it defines an encoding that can support other MSD
types. Here, the term "OSPF" means both OSPFv2 and OSPFv3.
This document is a product of the Link State Routing Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
