[0045] The present invention mainly provides a method for routing update, the main idea is: the backup control module backs up the routing prefix information on the main control module, and after the failure of the main control module, according to the generated routing table and the backup routing prefix information The information updates the forwarding table recorded by the interface module, and deletes the routing record corresponding to the routing prefix that exists in the backup routing prefix information and does not exist in the generated routing table in the forwarding table. It avoids the interruption of forwarding traffic caused by deleting the black hole route in the forwarding table after waiting for the aging time to arrive in the prior art, and improves the network traffic forwarding performance of the dual control module device.
[0046] The present invention proposes a method for routing update, which is applied in a dual control module device including an int...
