OMG! I was preparing for my CCNA and IPv6 seemed alien during a lot of the quizzes and sample test. The reason is because unless you have a book, most people on the Internet leave out A LOT of these small information that Cisco ASK ON THE EXAM!!! Thanks a lot Sunny!
They are used by routers. There are many routes from point x to point y. Routers can choose any next stop, but the closest stop is the best. Anycast means anyone is all right, but the closest one would be better and more efficient. Let me know if I did not make myself clear.
Hi Sunny. You said Any cast IP we used for the routers, so it does means if PCs has anycast IP it'll not work? As I remember from cisco class, it said PCs can it use.SO now I'm confused a little bit =)
@Mr. Elik: when we create a PROFESSIONAL network, we assign the task/function of network to whom? TO NETWORKING DEVICES! = SWITCHES! No matter the brand, a GROUP of PCs (=the area that we can configure as "anycast") will professionally be connected together to a SWITCH! Not to EACH other!!!! Long is gone the time of coaxial bus cables linking together dozens of PCs to a .. hub! Your question regards a topology long gone from the history of IT architecture! Is it more clear now? Thank you!
The solicited node example has a leading 0 in the unicast address, but not in the multicast address. Is there a reason for this? I thought all leading 0's were removed to shorten IPv6 addresses? 2001::01:800:200E:8C6C FF02::1:FF0E:8C6C
question how is it possible to have same ip? i know ip suppost to be unique than how can it be duplicated? isn't its gives an error of duplicate ip? *feeling a bit confused*
Hi Sunny, In regards to Multicast you said Prefix FF00, Although I learnt from Cisco that Multicast is FF02 and also checked on Google which give me same result.
You are correct. Specific multicast IPv6 always starts with FF02::/16. In this video, FF00::/8 means the first two characters are fixed (8 bits, that is why we use subnet mask short hand symbol ::/8). IPv6 is very confusing. I can say most of well-known IP6 multicast starts with FF02::/16, but sometimes it can starts with FF0x::/16. Thus, FF00::/8 is also correct because it can include other types of multicast. Thanks a lot for your inquiry and research. I like it.
If I understand correctly, FF00 is for all groups whereas FF02:1 addresses specific segments or LANs. FF02:2 contacts all routers in a segment. I agree IPv6 takes time to fathom.
Great vids as always, unsure why your way of explaining click well with me and i understand the concepts you discuss straight away !
I am glad that it clicks well with you. That is my goal.

Glad it helped!
Hey man. Just wanted to ask how the CCNA went?
Thank you Sunny for clarifying this! you are a legend!
your videos are always very easy to learn,,thanks
Very helpful for my exam in 2 hours, thank you so much! :)
Great Video, Great Explanation!
Thank you!
Thanks for this, Sir Sunny!
My pleasure!
Thank you so much! This was very helpful for my class!
You are welcome, and thanks for your comments.
Thank you it helped me a lot! I still have a question though, what anycast addresses are used for? Concretely
They are used by routers. There are many routes from point x to point y. Routers can choose any next stop, but the closest stop is the best. Anycast means anyone is all right, but the closest one would be better and more efficient. Let me know if I did not make myself clear.
Excellent lesson.
This helped me a lot!
Your videos are awesome
Hi Sunny. You said Any cast IP we used for the routers, so it does means if PCs has anycast IP it'll not work? As I remember from cisco class, it said PCs can it use.SO now I'm confused a little bit =)
typically it is used for routers. PCs can be assigned to an anycast group, but it is rare to join a PC with other PCs.

thanks alot, hope i pass my test about this :)
Good luck !
Brilliant!

Mr. Sunny, you have to publish Cisco training lessons. I am very sure that it will be the best.
for real
question how is it possible to have same ip? i know ip suppost to be unique than how can it be duplicated? isn't its gives an error of duplicate ip? *feeling a bit confused*

Hi Sunny, do you have any videos on IPv6 subnetting?
not yet.
@@sunnyclassroom24 Will you be making any? We could really use your help with it!

I've just realized what an absolute mess IPv6 is... There needs to be an IPv6.5 to clean it up
play in 1.5 speed . Thank me later
Thank you for your time!
A lot of information 😢
And the exams are soon 😂😢
