A first network device obtains a first route, where the first route includes a first route prefix. The first network device advertises a second route, where the second route includes a subnet prefix and a path identifier, and a range of the subnet prefix includes a range of the first route prefix.

Route advertisement method and related device

A communication method and apparatus are provided, so that packets of different services can be sent, based on a segment routing (SR) technology, on the same path specified by an SR policy. This addresses the significant limitation in the implementation of dual-stack reconstruction, and enhances communication efficiency. In the method, after receiving a first packet, a first network device forwards the first packet to a second network device based on a path specified by an SR policy. A destination endpoint specified by the SR policy is the second network device. An identifier of the destination endpoint includes a first IP address of the second network device and a second internet protocol (IP) address of the second network device.

Communication method and apparatus

A binding segment identifier processing method and a device are provided. The method includes a network device receives a message sent by a controller, where the message includes type information and a segment identifier, and the type information indicates that the segment identifier is a binding segment identifier BSID. The network device performs a processing action on the BSID based on the type information. According to embodiments of this application, the network device can identify the BSID, to resolve a technical problem that an incorrect processing result is caused when a segment identifier list of the network device includes the BSID.
