DOI: 10.17487/RFC8491
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 Segment ID (SID) stack can be
supported in a given network. This document only defines one type of
MSD: Base MPLS Imposition. However, it defines an encoding that can
support other MSD types. This document focuses on MSD use in a
network that is Segment Routing (SR) enabled, but MSD may also be
useful when SR is not enabled.
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.
This announcement is sent to the IETF-Announce and rfc-dist lists.
