How do I enable forwarding on Cisco Express?
Also question is, how do I enable CEF?
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.
Likewise, how do I know if my CEF is enabled? Confirm that CEF is enabled on a particular interface.
- Use the show cef interface x/x command to look for "IP CEF switching enabled," or "IP distributed CEF (dCEF) switching enabled."
- Use the show ip interface command to display the enabled Cisco IOS switching methods.
Beside this, what is IP CEF Cisco command?
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.
Which feature eliminates the need for Cisco Express Forwarding to maintain a route cache?
Forwarding Information Base Because there is a one-to-one correlation between FIB entries and routing table entries, the FIB contains all known routes and eliminates the need for route cache maintenance that is associated with switching paths, such as fast switching and optimum switching.
