Abstract: A method for advertising a bit error includes that an intermediate node in a first tunnel detects that a bit error rate of a packet sent through the first tunnel exceeds a threshold; and the intermediate node sends a first packet to an egress node in the first tunnel through the first tunnel, where the first packet indicates that a bit error has occurred in the first tunnel, the first packet further instructs the egress node to send a second packet to an ingress node in the first tunnel, and the second packet indicates that the bit error has occurred in the first tunnel. The foregoing method can be used to transfer bit error information, so as to implement associated protection switching of services.
