    • Techniques are described for maintaining a forwarding information base (FIB) within a packet-forwarding engine (PFE) of a router, and programming a packet-forwarding integrated circuit (IC) with a hardware version of the FIB. Entries of the hardware version identify primary forwarding next hops and backup forwarding next hops for the LSPs, wherein the packet-forwarding IC includes a control logic module and internal selector block configured to produce a value indicating a state of the first physical link. The selector block outputs one of the primary forwarding next hop and the backup forwarding next hop of the entries for forwarding the MPLS packets based on the value in response to the packet-processing engine addressing one of the entries of the FIB for the LSPs. Packets are forwarded with the PFE to the one of the primary forwarding next hop and the backup forwarding next hop output by the selector block.
    • 描述了用于在路由器的分组转发引擎(PFE)内维护转发信息库(FIB)的技术,并且利用FIB的硬件版本来编程分组转发集成电路(IC)。 硬件版本的条目识别LSP的主转发下一跳和后续转发,其中分组转发IC包括控制逻辑模块和内部选择器块,其被配置为产生指示第一物理链路的状态的值。 选择器块输出主要转发下一跳和用于转发MPLS分组的条目的备用转发下一跳,该响应于响应于分组处理引擎寻址用于LSP的FIB的条目中的一个的值。 分组与PFE一起转发到主转发下一跳和选择器块下一跳输出的备份转发。
