Abstract
This application provides a method for forwarding a packet in an SRv6 service function chain, an SFF, and an SF device, and belongs to the field of communication technologies. In this application, an End.PT.SID is used to identify that the SFF forwards an SRv6 packet to the SF device without stripping an SRH. Based on the End.PT.SID, the SFF does not strip the SRH in the SRv6 packet, but sends the SRv6 packet to the SF device. In addition, the SFF includes a control flag in the SRv6 packet, so that the control flag is used to identify a scenario in which an IPv6 extension header needs to be offset. The SF device directly offsets the IPv6 extension header in the SRv6 packet based on the control flag, to skip the SRH for service processing.
