C. Pignataro: AUTHOR [+4]
Seamless Bidirectional Forwarding Detection (S-BFD), specified in [RFC7880], is a simplified mechanism for using BFD with many negotiations eliminated. This is achieved by using 4-octet discriminators, unique within an administrative domain, to identify the network targets. These S-BFD Discriminators can be advertised by the IGPs, and this document concerns itself with OSPF. Specifically, this document defines a new TLV (named the S-BFD Discriminator TLV) to be carried within the OSPF Router Information (RI) Link State Advertisement (LSA) [RFC7770].

OSPF Extensions to Advertise Seamless Bidirectional Forwarding Detection (S-BFD) Target Discriminators
This document defines a new OSPF Router Information (RI) TLV that allows OSPF routers to flood the Seamless Bidirectional Forwarding Detection (S-BFD) Discriminator values associated with a target network identifier. This mechanism is applicable to both OSPFv2 and OSPFv3.
