Abstract
A communication method includes a first network device that receives a service packet from a first endpoint device, where a destination media access control (MAC) address of the service packet is a specific local MAC address of a second endpoint device, the specific local MAC address includes an indication prefix and location information, the indication prefix indicates that the specific local MAC address includes the location information, and the location information indicates an access location of an endpoint device in a network. The first network device determines an egress port from a preset routing table based on the location information in the specific local MAC address of the second endpoint device, and sends the service packet through the egress port, where the routing table includes the location information and the egress port corresponding to the location information.
