Thanks Panda

[@nethlidahanayake2138]

Excellent! Got OSI knowledge from this.

[@itfreetraining]

Thanks. Glad we could help.

[@itfreetraining]

Thanks for the comment. Glad you liked the video.

[@itfreetraining]

Thanks, glad to hear that your found the video useful

[@itfreetraining]

Thanks very much.

RIP is a layer 3 protocol (network layer), but the diagram in the video shows it's a layer 7 (application layer) protocol.

[@itfreetraining]

There is some debate over this one. Here you can find it listed as layer 3. en.wikipedia.org/wiki/List_of_network_protocols_(OSI_model)#Layer_3_protocols_.28Network_Layer_management.29Here you can find it listed as the application layer.en.wikipedia.org/wiki/Routing_Information_ProtocolThe question I think you need to ask is do you consider RIP a routing protocol as opposed to an
application that affects the routing table? Depending on the answer will determine which layer it operates at.
Since the video is primarily based on understanding what the OSI model is, to reduce the confusion in the future I will remove the RIP protocol from the diagram.
Thanks for your feedback.

[@itfreetraining]

Never heard that one before. Nice.

[@azedullete7979]

i learn a lot in this video. thanks

Thanks very much.

[@BijouBakson]

I'm afraid this course is nor detailed enough, nor accurate. I understand that it's pretty old and that by now you must have know that it needs amending. This is the only course I have seen here that needs amending, the rest of the courses I've seen are brilliant. Thank you for your work

[@aprilnine7057]

I must know who you are. Thanks for the video!:)

[@itfreetraining]

We're ITFreeTraining! And you're welcome. :)

[@shaakirshaikh9112]

Do you conduct any live remote trainings on upcoming technologies like Azure or AWS?

[@itfreetraining]

We don't do any live training sessions at this time however we're releasing new videos soon so stay tuned!

[@mcleanessiene4211]

Awesome

[@itfreetraining]

Thank you!

So If I have a C class adress,I want to subnet it into 3 networks. How many switches,routers do I need and what IP adress do the routers/switches get ? (or even firewalls etc) ?

[@ghettosuperstar2able]

have you got the full 70-410 course as yet?

[@itfreetraining]

Randolph welch No, we are still working on. Sorry for the delays.

[@ITFreeTest]

thanks

The term of the Layer 3 makes no sense. Isn't that should be like "Addressing" layer?

[@itfreetraining]

The Network layer works for the transmission of data from one host to the other located in different networks. It also takes care of packet routing i.e. selection of the shortest path to transmit the packet, from the number of routes available. The sender & receiver’s IP address are placed in the header by network layer.
The functions of the Network layer are :
Routing: The network layer protocols determine which route is suitable from source to destination. This function of
network layer is known as routing.Logical Addressing: In order to identify each device on internetwork uniquely, network layer defines an addressing
scheme. The sender & receiver’s IP address are placed in the header by network layer. Such an address distinguishes each device uniquely and universally.

bahut hi achha hai

I use your 70-640 and passed, but I do not see any 70-646

[@itfreetraining]

waleed awad Glad to hear that we helped you pass your exam. We do not have a course on 70-646.

[@ghettosuperstar2able]

waleed awad where did you pass your 70-640 That is a retired exam unless you done it a long time ago

[@waleedawad2031]

No it is not

[@ghettosuperstar2able]
