Understanding 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.

Been reading a lot of complicated nonsense online for hours but your video just nailed it. Straight to the point and really simple to grasp. Thanks

This whole networking technology engineering thing is like building more simple protocols on top of more primitive and more complex protocols, and at the other end this new technology seems like more complicated stuff. Duality of this is astonishing.

Thank you so much!! I reread the same section in my book multiple times but this just cleared it up!!

[sam]

your explanation is great, simple and concise, but please try to talk more slowly, it'll be much better.. thank you very much for your efforts (y)

and this is why "debug ip packet" does not show all traffic but only CPU switched one... for CEF traffic is needed "debug ip cef ..."

it was lovely and clear understanding teaching...

Great Video. But, I think, we need some clarification on Adjacency table. Because, I believe that Adj: Table is something that used for the Layer 2 information that we need in order to forward the packet and it is not at all related to the Routing table. Like something that maintains layer 2 Next hop address.

Again thank you so much for the upload :)

[gbhupenmail]

For those of you saying he's hard to understand or hard to follow, just use the controls on Youtube and slow the speed to .75. I admittedly had trouble understanding him at full speed, but at .75 it was no problem.
