Abstract: A filtered Forwarding Information Base (FIB) (the "complete local FIB") is used to determine how to forward packets, typically on line cards. The complete local FIB is generated by filtering (i.e., dropping or removing) extraneous entries in the standard global FIB of a router. This smaller FIB is then installed within the memory of a forwarding engine, possibly implemented as a single application-specific integrated circuit (ASIC), for use in determining how to forward packets, with the router forwarding packets accordingly.
Abstract translation: 过滤的转发信息库（FIB）（“完整本地FIB”）用于确定如何转发数据包，通常在线路卡上。 完整的本地FIB通过过滤（即，丢弃或删除）路由器的标准全局FIB中的无关条目来生成。 然后将较小的FIB安装在转发引擎的存储器内，可能实现为单个专用集成电路（ASIC），用于确定如何转发数据包，路由器会相应地转发数据包。
