CEF – Cisco Express Forwarding

CEF (Cisco Express Forwarding)

Cisco Express Forwarding (CEF) is advanced, Layer 3 IP switching technology. CEF optimizes network performance and scalability for networks with large and dynamic traffic patterns, such as the Internet, on networks characterized by intensive Web-based applications, or interactive sessions.

Enable CEF when your router has interface processors that do not support dCEF. To enable CEF, use the ip cef command in global configuration mode.

Enable dCEF when you want your line cards to perform express forwarding so that the route processor (RP) can handle routing protocols or switch packets from legacy interface processors. To enable dCEF operation, use the ip cef distributed command in global configuration mode as needed.
