For advertising In-situ Flow Information Telemetry (IFIT) node capabilities within the entire routing domain, this document extends a new optional TLV to the OSPF RI Opaque LSA, a new optional sub-TLV to the IS-IS Router CAPABILITY TLV, and a new Node Attribute TLV that is encoded in the BGP-LS attribute with Node NLRIs to carry IFIT node capabilities information. Such advertisement allows entities (e.g. a centralized controller) to determine whether a particular IFIT functionality can be supported in a given network.
