Simple question, Why if Cisco does not use CEF as the default switching in their routers?
They use as the default condition Fast Switching, that when a destination is not presented in the cache it fall back to the process-switching, which requires the IP Input process to give some attention to the packets waiting..... do not get it
CEF == Cisco Express Forwarding owned/written by Cisco and in Cisco hardware they use Fastswithing.... :S
