Question: 1 / 655

What types of CEF are utilized in chassis-based environments?

Basic and Advanced CEF

Flat and Routed CEF

Accelerated CEF and Distributed CEF

In chassis-based environments, the types of CEF (Cisco Express Forwarding) utilized are Accelerated CEF and Distributed CEF.

Accelerated CEF enhances performance by offloading certain functions to specialized hardware, allowing for faster data packet processing. It helps achieve high throughput and efficiency by leveraging the capabilities of the hardware forwarding plane.

Distributed CEF, on the other hand, allows for the distribution of the forwarding table across multiple line cards within the chassis. This architecture enhances scalability and redundancy, ensuring that forwarding decisions can be made closer to the data path, thereby minimizing latency and maximizing performance.

The combination of these two types of CEF in a chassis-based environment maximizes the effectiveness of packet forwarding and optimizes resource utilization, which is essential for handling high volumes of network traffic efficiently.
