Abstract: This application discloses a packet processing method that is applied to an EVPN, where the EVPN includes a first network device and a second network device. The method includes: receiving, by the first network device, a VXLAN packet sent by the second network device, where the VXLAN packet includes a path identifier and a service packet, the path identifier indicates a path from the first network device to a VNF device through an IPU, and the service packet includes a destination IP address; determining, by the first network device based on the path identifier, first routing information; and forwarding, by the first network device, the service packet to the VNF device via the IPU based on the first routing information and the destination IP address.
