Abstract

Various embodiments are disclosed for increasing Layer-3 LPM (longest prefix match) routing database in a network platform. In some embodiments, chipsets in fabric modules (FMs) can be partitioned into multiple banks. Network traffic can be directed towards a corresponding bank in the FMs by using a LPM table on a line card (LC). Entries in the LPM table on the LC can be programmed either statically or dynamically based upon LPM routes that are dynamically learned.
