Abstract: According to a communication method, a local device and a peer device notify each other through a border gateway protocol (BGP) message whether the local device and the peer device have a control word processing capability. When the peer device also has a control word processing capability, the peer device uses a service packet to carry a control word. When the local device has no control word processing capability, no control word is carried when the peer device sends a service packet to the local device.

Abstract: This application discloses a communication method. According to the method, a local device and a peer device notify each other through a BGP message whether the local device and the peer device have a control word processing capability. When the peer device also has a control word processing capability, the peer device uses a service packet to carry a control word. When the local device has no control word processing capability, no control word is carried when the peer device sends a service packet to the local device. In this way, normal communication between a network device having a control word processing capability and a network device having no control word processing capability is effectively ensured, and service transmission reliability is improved.
