Abstract: A method for performing bidirectional forwarding detection (BFD) on an aggregated link between a first network device and a second network device, where the first network device sends, to the second network device, information used to establish at least two BFD sessions. The first network device receives information that is used to establish at least two BFD sessions and sent by the second network device. The first network device respectively establishes BFD sessions between at least two pairs of ports according to the stored information and the information sent by the second network device. The first network device determines whether at least one BFD session in the established BFD sessions is up. If at least one BFD session in the established BFD sessions is up, the first network device determines that the aggregated link between the first network device and the second network device is available.
