description Systems and methods are described that reduce the amount of forwarding table state on components within routers. This is performed by having a router line card generate a prefix-request message to its central processor which contains a full routing table. Line cards only populate their forwarding tables for packets needed to transmit. By being only concerned with information of packets that are traversing each line card, the amount of required memory and processing required may be reduced for a complete forwarding table.
