Can someone explain how exactly CEF reduces the work on the CPU when the CEF Adjacency and FIB both reside in the Route Processor just like the Route table? This link doesn't exactly say how the CPU load is reduced. http://www.cisco.com/en/US/docs/ios/12_2/switch/configuration/guide/xcfcef.html#wp1000998
TIA.

CEF appears to accomplish packet forwarding in more efficient manner by reducing both the CPU work involved in forwarding a packet, and by reducing the CPU work keeping various caches current.
