    abstract =  {This document discusses the use cases why OSPF (Open Shortest Path First) distributing flow specification (FlowSpec) routes is necessary. This document also defines a new OSPF FlowSpec Opaque Link State Advertisement (LSA) encoding format that can be used to distribute FlowSpec routes. For the network only deploying IGP (Interior Gateway Protocol) (e.g. OSPF), it is expected to extend IGP to distribute FlowSpec routes. One advantage is to mitigate the impacts of Denial-of-Service (DoS) attacks.},
