This document defines a way for an Open Shortest Path First (OSPF) router originating the RI LSA to announce IFIT node capabilities within the entire routing domain. A new optional TLV is extended to the OSPF RI Opaque LSA [RFC7770] to carry the IFIT node capability information. Such advertisements enable IFIT applications in an operational network domain. Here, the term "OSPF" includes both OSPFv2 and OSPFv3.
