Abstract
The application provides a routing method which includes configuring a first path and a second path in charge of load sharing for a data flow, and configuring a third path in charge of reroute protection. A first group entry is generated for instructing the forwarding device to use the first path and the second path as load-sharing paths and use the third path to perform reroute protection on the first path and the second path. A flow entry for instructing to perform an operation of going to the first group entry is generated.
