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.

Abstract translation: 公开了用于在网络平台中增加第3层LPM（最长前缀匹配）路由数据库的各种实施例。 在一些实施例中，织物模块（FM）中的芯片组可以被划分成多个组。 通过使用线路卡（LC）上的LPM表，网络流量可以指向FM中的相应银行。 可以根据动态学习的LPM路由，静态地或动态地对LC中的LPM表中的条目进行编程。
