Abstract: A first network device sends a border gateway protocol (BGP) message to a second network device. The BGP message includes Ethernet virtual private network network layer reachability information (EVPN NLRI) and first information. The first information indicates a first maximum rate at which the second network device sends traffic to the first network device based on the EVPN NLRI.

According to the method in this application, less public network bandwidth is occupied, and overheads of the network device can be reduced.

The drum motor drives the drum to rotate at a set power output, the locking structure generates a locking action for locking the drum, and until an output current of the drum motor is larger than a rated current, it is determined that the drum is locked by the locking structure; by comparing the output current of the drum motor with the rated current, until the output current of the drum motor is larger than the rated current. Whether the drum is locked by the locking structure or not can be accurately determined through the above determination, and therefore the drum locking accuracy can be improved.
