    摘要: A method for failure detection on a bidirectional forwarding link mainly includes: sending, by one side of a BFD session, a BFD packet to the opposite side of the BFD session, and detecting a BFD packet sent by the opposite side, and starting, by the local side of the BFD session, BFD session detection when receiving a first BFD packet sent from the opposite side. By the method of the invention, it can be avoided that a router misinforms that failure occurs on a BFD session link due to difference of delays needed to deliver a BFD session parameter from a negotiation module of the router to a detection module.
