Displaying Multi-VRF CE Status

You can use the privileged EXEC commands in Table 36-15 to display information about multi-VRF CE
configuration and status.
For more information about the information in the displays, refer to the Cisco IOS Switching Services
Command Reference, Release 12.2.
Configuring Protocol-Independent Features
This section describes how to configure IP routing protocol-independent features. These features are
available on switches running the IP base image or the IP services image; except that with the IP base
image, protocol-related features are available only for RIP. 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 from
the Cisco.com page under Documentation > Cisco IOS Software > 12.2 Mainline > Command

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
