Frame relay on CCNA training?

Question

Cisco

Somehow I went through CCNA training and it still remains a mystery to me why they teach Frame relay there? Why not give the basics of MPLS, instead of obsolete technology? Or maybe I don’t know something and yet FR is a common technology? Who knows where it is now used?

Answer 1

Nowhere except for a thread of very seedy cases.
Apparently they just teach out of habit.

Answer 2

The mystery of nature ... Perhaps, to understand that "not a single ethernet."
But the concept of MPLS IMHO will be complicated for CCNA. They are still learning how to forward IP packets.
And what's the point of learning MPLS without VPN or TE? Well included LDP. Well, the labels have spread. As a result, nothing has changed, only headers have increased by 4 bytes, and somewhere deep inside the router, he began to look at a different header when transmitting a packet, with the same result ... They will ask the teacher “why did we enter mpls ip on the interfaces?” - and that has nothing to say except "well, then it will be possible to set this up again."

Answer 3

A good example of an NBMA environment, nothing more. It is useful for the horizon, in real life it is no longer found.

Answer 4

one CCIE response:

I asked this same question to some folks at Cisco when the CCIE R&S 4.0 update was released and it still had FR in it. Their response was basically that companies they polled that want to hire Cisco Certified individuals still want candidates to understand FR. I know of a few networks that still use frame relay today, but for most people the functionality has been replaced by MPLS L2 and L3VPNs and metro ethernet as you say.

Personally, I've never worked in a production environment that used frame relay, but I still know it because almost all of my Cisco certifications - including both CCIE tracks - required me to know it.

Answer 5

FR is a thing of the past, in the last update to the CCNA course (100-101 and 200-101) FR was removed, in CCIE R&S too.
