Abstract
The embodiment of the present application discloses a method and device for path restoration, the method comprising: a first routing device obtains and sends first aggregation information to a management device, the first aggregation information includes an identifier of a second routing device and at least one outgoing interface identifier of the first routing device, and the at least one outgoing interface of the first routing device is used for the first routing device to send a message to the second routing device; then, the management device can determine the restoration path from the first routing device to the second routing device based on the first aggregation information and the adjacency information in the first LSDB. In this way, each routing device aggregates the routing information of the routing device to other routing devices in the network domain to obtain the aggregation information, and reports the aggregation information to the management device as the data basis for the management device to perform path restoration, which can ensure that the restoration path obtained by the management device is completely consistent with the real forwarding path, and provides a reliable basis for fast and accurate troubleshooting in the network domain.
