Abstract
Exemplary methods for maintaining a shared forwarding table in a forwarding plane include a first network device operating in a forwarding plane receiving information associated with a first forwarding table from a second network device operating in a control plane, the information including a plurality of entries and precedence information, the precedence information indicating a priority of the plurality of entries of the first forwarding table. The methods further include for each entry of the first forwarding table, determining whether the entry should be inserted in the shared forwarding table based on the precedence information of the first forwarding table and precedence information contained in the shared forwarding table, wherein the precedence information contained in the shared forwarding table indicates a priority of each corresponding entry stored in the shared forwarding table.
