My life is now complete, this is SO easy and down to earth explanation, beautiful, I wish other IT videos in you tube were like this and made so much sense...
Hello Nadim- Thanks for the great question. One example when a L2 broadcast is used, is when computer A needs to learn it's default gateway's L2 (hardware MAC) address. It would use an ARP (address resolution protocol) message, which would be sent out to the L2 broadcast address of ff:ff:ff:ff:ff:ff (or all 1's in binary). Keith
Hi Jeff- Great question. Lots of Microsoft services, still use broadcasts (we would still see those). If we are running an older routing protocol such as RIP v1, it uses broadcasts. ARP caches entries that haven't been used in a while will time out, and then if a client needs to re-learn an ARP mapping, it will ARP again (which would be a broadcast again). Thanks for the question! Keith
Very nice and informative, now when it is usually said that the switch is intelligent and a hub is a dumb device, then for a 48 port switch working a default VLAN 1 , how or when does it really send the traffic by learning mac address of PCs connected to the ports thus not replicating to all the ports in the broadcast domain
Hello Keith if the switch learn all the MAC address of all the computer and default gateway connected is there any broadcast happening or any type of broadcast after learning all the mac address of every devices to connected to the switch

You are the best instructor so far.
This is from far the BEST explanation i have seen about Broadcast domain !!
Thanks,
merci beaucoup !!!

Probably one of the simplest explanations I've had of this concept...and the brief breakdown of Layer 1, 2 & 3 was great too
Thanks for the feedback!
Great explanation.Thank you so much.
Simply The BEST explanation!

loved this man, clearly explained. Thanks a lot!
I'm new in studying networking and this video helps me a lot in understanding this topic. Thanks!
really useful! I'm currently doing my HND in Networking and this has helped me to understand Broadcast domains!
Thanks a lot, great simple clear explanation.
Your videos are great Keith!
Sir it was so interesting and I love the way you teach...
Thanks for the feedback! It is very much appreciated and I am glad to hear you enjoy this MicroNugget.

beautifully explained. Thanks heaps :)
Thanks you thats so very helpful 👍👍👍
very good explaination thank you!
Awesome Video!
Thank you Chris!
Thank youuuuu
u explained better than my lecturer did
thank you very much

thx keith
Sir what are the collision domain, half duplex and full duplex I'm really confused in these things?
VLAN = From one network create multiple independent networks
What else is an example of layer 2 address other than ff ff ff ff ff ff ?
