Configuring Protocol-Independent Features

This section describes how to configure IP routing protocol-independent features. For a complete
description of the IP routing protocol-independent commands in this chapter, see the "IP Routing
Protocol-Independent Commands" chapter of the Cisco IOS IP Command Reference, Volume 2 of 3:
Routing Protocols, Release 12.2.

Configuring Cisco Express Forwarding

Cisco Express Forwarding (CEF) is a Layer 3 IP switching technology used to optimize network
performance. CEF implements an advanced IP look-up and forwarding algorithm to deliver maximum
Layer 3 switching performance. CEF is less CPU-intensive than fast switching route caching, allowing
more CPU processing power to be dedicated to packet forwarding. In dynamic networks, fast switching
cache entries are frequently invalidated because of routing changes, which can cause traffic to be process
switched using the routing table, instead of fast switched using the route cache. CEF use the Forwarding
Information Base (FIB) lookup table to perform destination-based switching of IP packets.
