This application provides a method for bit error rate detection, and a network device. The method includes: sending, by a first network device, a first notification packet to a second network device, where the first notification packet is used to instruct the second network device to perform bit error rate detection, the first network device is an ingress node of a first LSP, and the second network device is a downstream node, on the first LSP, of the first network device; and receiving, by the first network device, a second notification packet sent by the second network device, where the second notification packet carries a second bit error rate, the second bit error rate includes a first bit error rate of a first interface of the second network device, and the first interface is an interface that receives an MPLS packet that is sent by the first network device through the first LSP. By using the technical solutions provided in embodiments of the present invention, the first network device can perceive a bit error rate of the second network device, thereby helping ensure reliability of MPLS packet transmission in an IP RAN solution. |
