1. A method, comprising:
obtaining, by a session management network element, virtual local area network (VLAN) information of a first port, wherein the first port is of a first user plane network element and corresponds to an established protocol data unit (PDU) session of a first terminal, and the first user plane network element serves the first terminal;
generating, by the session management network element, first routing information and second routing information based on the VLAN information of the first port, wherein the first routing information is configured to be used by the first user plane network element to handle a first packet, the first packet is an uplink packet of the first terminal received by the first user plane network element through the first port, the second routing information is configured to be used by the first user plane network element to handle a second packet, and the second packet is a downlink packet sent by the first user plane network element to the first terminal through the first port; and
sending, by the session management network element, the first routing information and the second routing information to the first user plane network element.
