摘要： A packet processing method and a network device is disclosed. The method includes a first network device obtains a packet. The first network device adds first indication information and second indication information to the packet, to obtain an updated packet, where the first indication information and the second indication information are located in a multi-protocol label switching MPLS packet header of the updated packet, the first indication information indicates a network slice corresponding to the packet, and the second indication information indicates a forwarding path of the packet. The first network device sends the updated packet to a second network device. A network slice corresponding to a packet and a forwarding path of the packet are respectively indicated in an MPLS packet header via different indication information.
