1. A network device, applied to a first network device in a network, the network device comprises:
one or more memories configured to store instructions that, when executed by one or more processors coupled to the one or more memories, cause the network device to:
send a plurality of first routes to a second network device in a parallel transmission manner, wherein the second network device use the plurality of first routes to refresh a routing table; and
after determining that the second network device has received the plurality of first routes, send an end indication to the second network device, wherein the end indication indicates that the sending of the plurality of first routes to the second network device has been completed,
wherein the first network device comprises a routing processor and a transceiver, the routing processor runs a routing protocol, and the transceiver runs a transmission protocol; and wherein the one or more processors are further configured to execute the instructions to cause the network device to:
send, by the routing processor, the plurality of first routes to the transceiver;
receive, by the transceiver, one or more notification messages from the second network device;
determine, based on the one or more notification messages from the second network device, whether the second network device has received the plurality of first routes; and
after determining that the second network device has received the plurality of first routes, send, by the routing processor, the end indication to the second network device to indicate that the sending of the plurality of first routes to the second network device has been completed.
