System and method for FIB aggregation

A method for installing FIB changes, comprising the steps of:

• providing a forwarding information base (FIB) aggregation system, including a router having a control plane with a routing information base (RIB) and a data plane with a forwarding information base (FIB), and an aggregation module at the control plane;
• receiving a plurality of routes at the aggregation module from the RIB;
• aggregating the plurality of routes via the aggregation module to generate an aggregated FIB;
• downloading the aggregated FIB into the FIB;
• copying the aggregated FIB with one or more flags representing a processing decision to generate an aggregated FIB copy;
• storing the aggregated FIB copy at the aggregation module;
• receiving a router update at the RIB and updating the RIB according to the router update;
• transmitting the router update to the aggregation module after it updates the RIB;
• and
• updating the aggregated FIB copy incrementally, via the aggregation module, according to the router update.
