Cisco Express Forwarding (CEF) switching is a proprietary form of scalable switching intended to tackle the problems associated with demand caching. With CEF switching, the information which is conventionally stored in a route cache is split up over several data structures. See more Figure 1 illustrates the process by which a routing update packet is sent to the Gigabit Route Processor (GRP) and the resultant forwarding update messages are sent to FIB tables on the line cards. For clarity, the … See more Once the line cards have enough forwarding information to determine the path through the switching fabric (for instance, the destination of the next hop), the 12000 router is ready to forward packets. The next … See more When the line cards have enough forwarding information to determine the path through the switching fabric (for example, the destination of the next hop), the 12000 router is ready to forward packets.
