The data structures that provide optimized lookup for efficient packet forwarding include:įorwarding Information Base (FIB) table-Cisco Express Forwarding uses a FIB to make IP destination prefix-based switching decisions. The Cisco Express Forwarding code is able to maintain these data structures in the RP, and also in slave processors such as VIPs in the Cisco 7500 Series and LCs in the Cisco 12000 Series. With Cisco Express Forwarding switching, the information which is conventionally stored in a route cache is split up over several data structures.
Background InformationĬisco Express Forwarding switching is a proprietary form of scalable switching intended to tackle the problems associated with demand caching. Refer to Cisco Technical Tips Conventions for more information on document conventions.
IS IT OK TO DISABLE ADOBE CEF HELPER SOFTWARE
This document is not restricted to specific software and hardware versions. There are no specific requirements for this document. On the 12000 Series, the RP is known as the Gigabit Route Processor (GRP) and LCs are simply referred to as LCs.
For the 7500 Series, the RP is called the Route Switch Processor (RSP) and LCs are called Versatile Interface Processors (VIPs). Note: Depending on the platform on which Distributed Cisco Express Forwarding is configured, Route Processors (RPs) and Line Cards (LCs) are referred to differently.
