Packet processing method and related device

A packet processing apparatus, used in a first network device and comprising:

• a memory storing instructions;
• and
• a processor coupled to the memory;
• wherein the instructions, when executed by the processor, cause the apparatus to be configured to:
• receive a first service packet;
• in response to determining that a destination address of the first service packet matches a segment routing (SR) policy, determine, based on first indication information in the SR policy, whether a first segment list points to an endpoint of the SR policy, wherein the SR policy comprises endpoint information, and the endpoint information indicates the endpoint, wherein
• encapsulate the first service packet based on a result of whether the first segment list points to the endpoint of the SR policy, to obtain a second service packet;
• and
• forward the second service packet according to an SR path determined based on the first segment list.
