Abstract: Embodiments of this application provide a bit-forwarding ingress router, a bit-forwarding router, and an OAM test method, and pertain to the field of multicast networks. A first BFR receives an OAM request packet from a BFIR; the first BFR determines, according to the OAM request packet, that a destination BFR corresponding to the OAM request packet is the first BFR; and the first BFR obtains a first OAM response packet according to an ID of the BFIR, and sends the first OAM response packet to the BFIR. According to the method and the apparatus that are provided in the embodiments of this application, a problem that a BFIR cannot diagnose or handle a transmission fault when the fault occurs during transmission of a multicast packet can be resolved, which helps implement connectivity testing by using an OAM packet and enables testing of multiple BFERs.
