5 . The method according to claim 1 , wherein the third RPC indicates the second network device to return first data, and wherein the determining, by the first network device, the target invalid data in the second network device further comprises:

receiving, by the first network device, an error identifier returned by the second network device, wherein the error identifier indicates that second data referenced by the first data has been deleted; and

determining, by the first network device, based on the error identifier, the first data as the target invalid data in the second network device.

6 . The method according to claim 1 , wherein before the determining, by the first network device, the target invalid data in the second network device, the method further comprises:

establishing, by the first network device, a network configuration session with the second network device; and

receiving, by the first network device based on the network configuration session, information indicating a residual network configuration data clearing capability that is sent by the second network device and that is supported by the second network device.

7 . The method according to claim 1 , wherein the first RPC is a new RPC, wherein an input parameter of the new RPC comprises the information about the target invalid data that needs to be deleted; or

the first RPC is an extended RPC obtained by extending an existing RPC, wherein the extended RPC carries the information about the target invalid data that needs to be deleted.

8 . The method according to claim 1 , wherein after the sending, by the first network device, the first RPC to the second network device, the method further comprises:

reading, by the first network device, the target invalid data in the second network device; and

verifying, based on reading the target invalid data, whether the target invalid data is cleared.

9 . An apparatus, wherein the apparatus comprises:

at least one processor;

at least one non-transitory computer-readable storage medium storing a program to be executed by the at least one processor, the program including instructions to cause the apparatus to perform operations including:

determining target invalid data in a second network device,

wherein the determining the target invalid data in the second network device comprises:

sending a second remote procedure call (RPC) or a third RPC to the second network device; and

obtaining a first RPC, wherein the first RPC carries information about target invalid data that needs to be deleted; and

sending the first RPC to the second network device, wherein the first RPC indicates to the second network device to delete the target invalid data.

10 . The apparatus according to claim 9 , wherein the second RPC indicates the second network device to perform data difference comparison, and wherein the determining the target invalid data further comprises:

receiving a data difference comparison result returned by the second network device; and

determining, based on the data difference comparison result, the target invalid data in the second network device.

11 . The apparatus according to claim 10 , wherein before the sending the second RPC to the second network device, the operations further comprise:

receiving a basic event notification sent by the second network device, wherein the basic event notification indicates that invalid data exists in the second network device;

determining, based on the basic event notification, that the invalid data exists in the second network device; and

triggering the sending of the second RPC to the second network device.

12 . The apparatus according to claim 9 , wherein the third RPC indicates to the second network device to return first data, and wherein the determining the target invalid data in the second network device further comprises:

receiving the first data returned by the second network device; and

determining, in response to determining that second data referenced by the first data does not exist, that the first data is the target invalid data in the second network device.

13 . The apparatus according to claim 9 , wherein the third RPC indicates the second network device to return first data, and wherein the determining the target invalid data in the second network device further comprises:
