Abstract: Disclosed is a communication method. According to the method, a present device and a peer device instruct, by means of a BGP message, to each other whether they have a control word processing capability. When receiving the BGP message sent by the present device and carrying control word instruction information, the peer device determines that the present device has a control word processing capability. If the peer device also has a control word processing capability, the peer device would carry a control word when sending a service packet to the present device. If the present device does not have a control word processing capability, the BGP message sent to the peer device would not carry the control word instruction information, and the peer device would not carry a control word when sending a service packet to the present device. Therefore, the normal communications between a network device having a control word processing capability and a network device not having a control word processing capability is effectively ensured, and the reliability of service transmission is improved.
