Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below through specific embodiments and with reference to the accompanying drawings.
[0023] In the present invention, when the main control card is in normal operation, the main control card regularly sends the elegant restart message generated by the routing protocol and needs to be sent to all neighbor devices to the line card. When the main control card fails and needs to be restarted , the line card sends a graceful restart packet to the neighbor device. When the main control card in a distributed network device is restarted, the line card does not need to wait for the main control card to start and run the routing protocol. The line card directly sends a graceful restart message to the neighbor device, which shortens the sending time of the graceful restart message and improves the distributed network. The success rate ...
