C) BFD multi-hop detection means that BFD can detect arbitrary paths between two systems that may span many hops or overlap in some parts
D) BFD and OSPF linkage is to associate BFD and OSPF, and notify OSPF through BFD's rapid sensing of link failures, thereby speeding up OSPF Response to changes in network topology
