1. A route configuration method implemented by a session management network element, wherein the route configuration method comprises:
determining a first intermediate user plane network element that serves a first terminal in a virtual network group and maintains communication between a first anchor user plane network element and a first access network device accessed by the first terminal;
obtaining first address information of a second terminal;
obtaining first uplink tunnel information of a second anchor user plane network element, wherein the second anchor user plane network element meets a first condition and a second condition,
wherein the first condition is that the second anchor user plane network element provides an anchor service for the second terminal in the virtual network group and the second terminal is located in a service area of the second anchor user plane network element; and
wherein the second condition is that the second anchor user plane network element is different from the first anchor user plane network element;
generating, based on the first address information and the first uplink tunnel information, a first routing rule corresponding to the second terminal, wherein the first routing rule is for sending, to the second anchor user plane network element, a first packet comprising the first address information as a first destination address; and
sending, to the first intermediate user plane network element, the first routing rule.
