A method, apparatus and computer program product for maintaining port state tables in a forwarding plane of a network element are presented. The state of a first set of ports associated with a first Forwarding Data Unit (FDU) are periodically determined, the first FDU being one of a plurality of FDUs. The determined state is used to update a first port state table of the port state database associated with the first FDU. The determined state is transmitted to each other FDUs on the network element to enable each of the other FDUs to store the state of the first set of ports in a port state database local to each of the other FDUs. The port state database is used by the forwarding plane to perform fast reroute of packets. |
