This document defines a way for an Intermediate System to Intermediate System (IS-IS) routers to advertise IFIT (In-situ Flow Information Telemetry) capabilities. This document extends a new optional sub-TLV in the IS-IS Router CAPABILITY TLV [RFC7981], which allows a router to announce its IFIT node capabilities within an IS- IS level or the entire routing domain. Such advertisements enable IFIT applications in the network domain.
