The process looks correct. The issue is that they all are on the same network. These are IP addresses on the same 10.0.0.0/24 network.IF the example was three networks 10.0.4.0/24, 10.0.5.0/24, and 10.0.6.0/24 then then the third octet would be summarized as you show in the fourth. Route summarization should have a smaller netmask than that of the original contiguous networks being summarized.So taking your example and because the third octet is where the change happens the first two octets don't change:10.0.00000100.00000000 (10.0.4.0/24)10.0.00000101.00000000 (10.0.5.0/24)10.0.00000110.00000000 (10.0.6.0/24)In the third octet you will see, as you show in the video, starting from left to right, all bits are same up to the first 1 in the third octet.The bits that are the same are 8+8+6 =22.The new summary route would be 10.0.4.0/22
When I watched her video and i was impressed and gave her compliment in comment section as"beauty with brains" But after reading your comment I am taking my words back and commenting "shit" Intead of "brains" That will be justice 😎
Nice explanation, and correct too, but you are confusing host addresses for routes(which are meant to be network addresses). That's why the prefix-length increase from /24 to /30, whereas it is supposed to decrease. I think the proper addresses for the routes should be like - 10.0.4.0/24, 10.0.5.0/24, 10.0.6.0/24, and the summary route will be 10.0.4.0/22.
it is special video with wrong examples and wrong answer for detect stupid people in comments who like "wow thank you it's now crystal clear for me!" but actually don't understand single piece of shit in summarization
I appreciate being able to find a short, clear video on a topic like this instead of having to watch multiple 20 minute to 2 hour videos on IPv4 to find it.
I literally just started trying to figure out Route summarization on a website, and I almost had it, but I didn't understand how they got (in your particular example), the "4"in the last octet. The way you explained it, turning everything past the "bits that are in common" to zeros, and then figuring out that binary value in decimal just made it click, *thank you* so much 😊👍🏻
After reading about route summarization in the ccna3 scaling networks course, I felt very confused. After watching your 3min video it all makes so much more sense. Thank you, you rock!
Thanks. I learned this through another set of videos, forgot it, and then bombed the summary route questions on the CCNA practice exam questions. This video was great review and would have been an effective way to learn it the first time as well. Thank you again for sharing.
Awesome and straight to the point, as a black man I found myself always clicking on male videos when searching so I asked myself how can I be a little less sexist today lol. I seen your video and went for it and I'm so glad I did you got straight to the point and very easy to understand. Thank you so much and keep up the great work, I'll keep watching you!
I was going to ask what the new prefix length was since you left it out but i saw in the comments how it would turn to be /30. Thanks for the discussions and video
Kim, the actual answer to your example is 10.0.0.0/24 as these IP addresses are all on the same network. Perhaps you meant 10.0.4.0/24 10.0.5.0/24 & 10.0.6.0/24? If you did then the summary would be 10.0.4.0/22
Странно, вы тут пытаетесь запихнуть 3 хоста в единый маршрут... Может быть .4, .5, .6 должны быть в 3 октете? /30 маска может адресовать только 2 хоста)
Use Boson Subnet Calculator, type in the host IP address and adjust the mask bits according to CIDR. It will provide the host range and one can adjust the mask bits so the host range can fit the network addresses
Do you have a video explaining the concept of summarization? This howto calculation is great and very helpful! However, I am still fuzzy on summarization.
Lol keep in mind this video is wrong... you are just one of those idiots (sorry to say so) who just comment how the video was super helpful without understanding shit.
Although the process is correct but there is issue that is they are all in the same network. So why would there be route summarization? How can subnet mask(prefeix is increasing after aggregation? 24 to 30? by just combining 3 network). It will be alright if the three networks would be 10.0.4.0/24, 10.0.5.0/24, and 10.0.6.0/24. Then rest of the process is good. The subnet mask would be 8 + 8 + 6 = /22 (last 2 digit in 3rd octet are changing, upto 6 digit is common)
Well, this just made route summarization easy. The method taught to us was too complex and would not be practical when taking the exam. Thank you so much!
i have a doubt. my question is completely different from yours (1. 10.100.0.0/16 10.102.0.0/16 10.104.0.0/16 10.101.0.0/16 ) how we can summarize this? please help
172.1.4.128/25 172.1.7.0/24 172.1.6.0/24 172.1.5.0/24 172.1.4.0/25 summary address i found is 172.1.0.4/21 am ii right Kim ? let me know Do you see an octet that looks interesting to you? I do. It’s the third octet. 4, 5, 6, 7, and yes, it’s a block size of 4. So you can summarize 172.1.4.0 using a mask of 255.255.252.0, meaning you would use a block size of 4 in the third octet. The IP addresses forwarded with this summary would be 172.1.4.1 through 172.1.7.254. what this paragraph means not understood ? can you explain because i got the summary address as 172.1.0.4/21 thank you !
nice one, brief and simple explanation. why did you stop making new videos i wonder.....(also, there is 7 thumbs down for this video? why? i don't get it...)
Thank you for the kind words. I really enjoyed making the videos, and would've liked to do more as I was teaching the content, but I just ran out of time. Maybe in the near future.

Hi, that was a quick explanation after a long time, I was checking the route summarization and finally got here.
Kudos to the simple method, thanks to you I know my summary route !!
Thanks! Glad to help!
wowoow so nice teaching skill....👏
Is this supernet?
Yes
Kim, the actual answer to your example is 10.0.0.0/24 as these IP addresses are all on the same network.
Perhaps you meant 10.0.4.0/24 10.0.5.0/24 & 10.0.6.0/24?
If you did then the summary would be 10.0.4.0/22
very helpful for quick review :) Many thanks!

Something wrong with the output subnet mask can't be /30
Good explanation
The CIDR Value for Route Sumarization is 10.0.0.0/30 ?
Mam you are the best you prooovide very easy and detailed methods to learn difficult things
thank you Kim , but if i had 3 subnet different in 2 octet which octet i should convert it into binary ?
great video, thank you Kim! keep up the good work❤
Thanks a lot Kim, do have other tutorials for CCNA prep
Thanks for the video sis.It makes me to understand well.But i had a question.how to find the prefix?

What about supernetting?
This is the only thing I don't get in Cisco.
Amazing stuff ma'am
is the CIDR Notation /30??
Wonderful explanation! You save me a lot of time!! Thanks
Nice mam you really teach well
Best Teacher ever. Subscribed !
Awe! Thank you!!
Thank you kim explantation clearly and easy .perfect
Thanks for the video sis...it makes me to understand well...but i had a question..how to find the prefix?

Thanks a lot Kim, finally i understand how to deal with 1 and 0 i was really confused before but now everything is crystal.

Hello this is nice explanation 👍 thank you.
This is such a good explanation! Thank you! You made it click
Thank you! This was simple and straight to the point.
Exact and perfect explanation.
Thanks a lot.
Thank you so much, Working for my Networking degree and this video helped a lot!
Glad to hear, good luck!
It would be better to add that the new CIDR notation will also change form /24 to /22
that is incorrect, mostly because she did this backwards and turned a /24 into a /30
the final slash notation would become /30 ? or remain /24 ? thankyou for your video explanation :)
The subnet mask would be /30
Thank you so much mam how easily you tell this I don't know how to express it. What an easy explaination mam thank you.
Hmmm what if they are VLAN subnets? as in i am configuring OSPF and adding only LAN subnets?
totally different topic man, also For the Greater Good
Arent they in same network

Can anyone tell me what will be the slash notation?

Do you see an octet that looks interesting to you? I do. It’s the third octet. 4, 5, 6, 7, and yes, it’s a block size of 4.
