The invention discloses a network
route convergence
processing method. According to the method, a preset non-
pruning multicast distribution tree is utilized as a fast channel, when
network topology is changed, after adjacent devices of a topological change source detect the topological change, a
layered service provider (LSP) message is generated according to topological
change type, and the LSP message is sent out through the fast channel, and then convergence
processing modules on the adjacent devices continue to carry out
route convergence process to the topological change event. After a device on the fast channel receives the LSP message, the message is transmitted, and at the same time, the message is sent to the convergence
processing modules for
route convergence process. The invention further provides a corresponding network route convergence processing device. By means of the network route convergence processing method and the network route convergence processing device, convergence of a whole network is enabled basically not to be limited by
network size and topological
change positions, and the convergence performance of the whole network is close to the convergence performance of a single device.
