Fast reroute for common network routes

摘要

In one example, a method includes identifying a plurality of common direct routes to computing devices that are associated with a common indirect route to the computing devices. The method also includes generating a direct route structure that is associated with an entry of a forwarding structure using a next hop list, wherein the next hop list comprises: (1) a reference that identifies the direct route structure, the direct route structure comprising a plurality of direct next hops associated with the common direct routes to computing devices, (2) and an indirect next hop associated with an indirect next hop to the computing devices. The method also includes configuring the next hop list to use the direct route structure to route network data. The method also includes forwarding, by the computing device, network data according to the forwarding structure and the direct route structure.
