Hi Jeremy, not sure if you noticed or if you can change it now but around the24:48 mark, 128 is shown in binary as 100000 instead of 10000000. Not a major issue and should be clear to most but some folks may find it confusing, especially beginners who are not so familiar with binary. Great content as always! 👍

Dear Jeremy, I have passed the CCNA exam. Thanks so much for your incredible training and this journey of learning through all of your videos. (Posting here since I love routing most of all) So grateful...
Even after completing a very good CCNA video training on Udemy, while watching this series of videos, I still find myself learning new things and my overall level of understanding increases. Thank you Jeremy!
I like how you include other things into complete CCNA course even though there are not specified in exam topic list. RIP and EIGRP tend to appear on job interviews and for obvious reason it’s good to know the answers.
I am preparing for my CCNP ENCOR exam and I am still getting back to your videos to better understand these topics. I have watched videos from several reputable resources and I still think you are THE BEST instructor!
The OPTIMAL wildcard is a /13 prefix which is 0.7.255.255. However, the question has three answers that have an exact match of 172 with the first octet of zero. the problem with these is that the second octet for all three of these does not have the range required of Class B network range of 20-26 (hence requiring a /13 prefix) to advertise BOTH networks. The first option of A is a massive network range prefix of /1 where there can be over 2 billion usable hosts. This is why it's the only answer that is correct. It's just extremely inefficient for a real network.
First I´d like to congratulate you for this wonderful work you are doing, it is amazing. I designed a similar topology in packet tracer and tried to use RIP and a remote server to allocate Ip´s to the PC´s, the routing table was populated and the routers could ping each other, what happened is that the pcs couldn´t get IP´s and even if I manually configured manually the pings didn´t succeed. But with EIGRP the pc´s could get IP´s and ping each other.
I'm still having a terrible time understanding EIGRP terminology its overly confusing despite Jeremys best effort to explain it. I feel like the terminology was purposely designed to be confusing.
I think this video was the most confusing, especially the wildcard masks. where a lot of the details were said instead of on screen as usual. Repeated it a couple of times and still confused on how to determine how many binary digits have to match. For instance, at 27:11, why does 172.16.1.0 have to match all /29 network bits. While at 28:15 only the first 5 bits?
I think you are the best instructor. Even though English is my third language, I don't have any problems understanding your explanations. Thank you, Jeremy!

For anyone having trouble with the wildcard masks, an easy way to figure it out is by adding both IP's after the network command together. If each IP is lower than the added total, it will cover it and activate EIGRP or OSPF. For example: network 128.0.0.0 127.255.255.255 - added together, those are 255.255.255.255. This command would actually cover any IP address. However, if you executed the command network 172.16.0.0 0.0.255.255, adding those together you'd get 172.16.255.255 and this would not cover an IP like 172.20.20.17 or 172.26.20.12 (both of which are higher) - If I'm wrong, please let me know though!

I was following along no problem, right up until the network command with the wildcard masks, it seems unnecessary to just invert the mask all of a sudden lol. I hope I'll learn there's a good reason for it some day!
I think it's just to distinguish wildcard masks (which identify which bits need to be matched in the 'network' command as well as other things like ACLs) from subnet masks (which identify a network range). You'll get used to them!
Auto-summary automatically converts the advertised routes to 'classful' addresses. For example, if trying to advertise a route to destination '192.168.1.16/28', auto-summary will change it to 192.168.1.0/24 (a regular class C network).
@@JeremysITLab I hope you are right. Our prof. Has been giving us practice quiz dumps with a bunch of muticast/unicast and sometimes anycast questions and answers on them
Hi Jeremy, I got confused in Quiz 2 36:58 here, where's both IP addresses are in Class B, I didn't understand how the network command become 128.0.0.0?
Hi Jeremy, I love your video so much,and I plan to follow your video course to pass CCNA in less three months. I have studed 11 lessions and may I ask how many lessions in total there are and when you will upload all the video? Thank you very much.
You can see how many lessons there will be here: th-cam.com/play/PLxbwE86jKRgMpuZuLBivzlM8s2Dk5lXBQ.html As for how many there will be, I'm not sure. Maybe about 50 'days' in total.
Here is a useful information on EIGRP AS ( autonomous system ) number. The AS number is a 16-bit value, allowing it to range from < 1 - 65,535 >. The AS number 0 is used to represent the '' default autonomous system '' or '' AS-wide scope''. AS number 0, therefore must not be used, because its a reserved number. When a router is configured with the AS ( autonomous system ) number 0, it indicates that the router is participating in multiple EIGRP "AS" number or domains without having a dedicated "AS" number for itself. This setup allows the router to act as a central point for information exchange between different EIGRP domains.
I commented in the VLSM video about using route aggregation (though I couldn't remember what it was called at the time) using RIP v1 you could use VLSM with route aggregation. I am sure the reason you don't mention it is because its either out the scope of the CCNA or route aggregation isn't used in the real world.
After your explanation of wildcard masks @ 29:08 in the video, did the network statement for the 172.16.1.0 network required to have a wildcard mask? If you had a network statement of 'network 172.16.1.0' wouldn't it default to a /16 network which would then include the ip address on the g2/0 interface on R1?
So I get how wildcard masks work and you explained it well. But what is the PURPOSE of the inversion? WHY is the subnet mask converted? It just seems so unnecessary but maybe I'm missing or misunderstanding the crux of it
Sir, at 15:30 gateway last resort is set to 10.0.34.1....if both 10.0.34.1 & 10.0.24.1 is treated equally in RIP...why is 10.0.34.1 choose over 10.0.24.1 ???
Hey. There is a simple trick for Wildcard Mask : Each decimal value (byte) of the result of (eigrp network + wildcard mask) Must be >= greatest corresponding decimal value of any interface IP address set in router AND
Hello ! I've watched from Day 1 to 25. Now, these topics are not very urgent for my current needs for networking (I don't have multiple paths!), I'm thinking of picking up from Day 30 (and watch the skipped videos later when I have more time) Are the topics in-between needed for understanding Day 30 and on ?
Just a short question regarding minute 7 of this video. You say there that 10.1.1.0/24 will become class A address so assumed to be /8. (10.0.0.0). Based on the logic of the following ones for RIPv1 should not this be assumed as /24 as it is ? so should not it remain a /24 ? Sorry if it's a stupid question!
Hey Jeremy! How many videos yet you're gonna Upload ? I've scheduled to finish Day 24 within two weeks, yesterday and today you're uploading a new one.
@15:36 I'm a little confused about the "default-information originate" command. Is this necessary? The default route is always in the routing table, so why wouldn't it naturally be advertised to the other routers?
Do you know if there will be another Boson Exsim and Netsim sale through your link? I am looking for more ways to practice and apply this information. Also are you able to do a video talking about how you have used your CCNA experience? What information have you used the most from your CCNA and CCNP? Hope that's not too much, and as always I appreciate the videos.
When Boson runs their next sale, I'll be sure to let everyone know ;) Currently I don't have a lot of time to make extra videos outside of the course content, but that's a good idea, I'll definitely make that video in the future :)
quiz 2 got me confused how if I use 0.15.255.255. way I do it is I take the block size so 172.20.20.17 & 172.26.20.12. so second octet if take block size of 16 to fit both 20&26 in one block so thats subnet of 255.240.0.0 .wild card mask=255.255.255.255-255.240.0.0 = 0.15.255.255.
Wildcard masks have an advantage of not having to be contiguous, so for example you could have a wildcard mask like 0.255.0.255, which matches only the first and third octets. Subnet masks have to be a straight series of 1s followed by 0s, like 255.255.0.0. Although, for EIGRP and OSPF I don't think you can even do things like that with wildcard masks, at least not in Cisco IOS.
Q2 in the quiz has left me confused. Even with binary written, still trying to understand the logic of how 128.0.0.0 is a match for 172.x.x.x. Are we not given the subnet mask on the exam for questions like this?
The subnet mask configured on the interfaces is irrelevant for activating ERIGP on them, so it doesn't matter. 128.0.0.0 127.255.255.255 matches both of those addresses because the wildcard mask 127.255.255.255 means only the first bit of the IP address has to match (it's the only bit that is a 0 in the wildcard mask). The first bit of 128.0.0.0 is a 1. 172.20.20.17 and 172.26.20.12 also have a first bit of 1, so they match the statement 'network 128.0.0.0 127.255.255.255'.
@@JeremysITLab so we cannot just take the subnet mask and convert it to wild card mask as you did with 172 network with slash 28 and that wild card mask was 0.0.0.15 so why we didn’t the same here?
@@wafa1203 You can do that if you want, feel free. Although notice that the question doesn't state the subnet mask configured on either of the interfaces, and also none of the answers use a 0.0.0.15 wildcard mask. In quiz questions like this, pick the correct answer from the available options, even if there are other possibilities that maybe correct. When using the 'network' command, there will always be lots of possibilities that will work to activate EIGRP on the interface.

The OPTIMAL wildcard is a /13 prefix which is 0.7.255.255.

I was following along no problem, right up until the network command with the wildcard masks, it seems unnecessary to just invert the mask all of a sudden lol.
I hope I'll learn there's a good reason for it some day!
I think it's just to distinguish wildcard masks (which identify which bits need to be matched in the 'network' command as well as other things like ACLs) from subnet masks (which identify a network range). You'll get used to them!
Thank you so much for this series of videos😊. I think two 0s are missing in the first subnet mask (see 24:47)
Yep, I've got that one in the Errata in the comments ;)
Just Awesome and God bless you Sir
Thank you Saurav :)
ধন্যবাদ স্যার,অনেক সহজ হলো
Thanks a lot Jeremy. I'd like to ask you about no auto-summary role I didn't grasp it well.
Auto-summary automatically converts the advertised routes to 'classful' addresses. For example, if trying to advertise a route to destination '192.168.1.16/28', auto-summary will change it to 192.168.1.0/24 (a regular class C network).
Thanks for the videos! I thnk you might have to update these. Multicast seems to be part of the CCNA as it is in some of the exam dumps I've seen
Multicast is not part of the CCNA exam topics.
@@JeremysITLab I hope you are right. Our prof. Has been giving us practice quiz dumps with a bunch of muticast/unicast and sometimes anycast questions and answers on them
God bless you for these videos
Thanks for all your comments :)
Jeremy do you have a Q and A section for your course ?
Feel free to ask comments in the comment section
thank you for the updates sir :)
Thanks for watching ;)
Hi Jeremy, I got confused in Quiz 2 36:58 here, where's both IP addresses are in Class B, I didn't understand how the network command become 128.0.0.0?
Great explanation..thank you a lot 💓 🙏 💛 Jeremy
Hi Jeremy, I love your video so much,and I plan to follow your video course to pass CCNA in less three months. I have studed 11 lessions and may I ask how many lessions in total there are and when you will upload all the video? Thank you very much.
You can see how many lessons there will be here:
th-cam.com/play/PLxbwE86jKRgMpuZuLBivzlM8s2Dk5lXBQ.html
As for how many there will be, I'm not sure. Maybe about 50 'days' in total.
Great video, Thanks!!!
Thanks :)
Here is a useful information on EIGRP AS ( autonomous system ) number. The AS number is a 16-bit value, allowing it to range from < 1 - 65,535 >.
The AS number 0 is used to represent the '' default autonomous system '' or '' AS-wide scope''. AS number 0, therefore must not be used, because its a reserved number.
When a router is configured with the AS ( autonomous system ) number 0, it indicates that the router is participating in multiple EIGRP "AS" number or domains without having a dedicated "AS" number for itself. This setup allows the router to act as a central point for information exchange between different EIGRP domains.
Looking forward for more videos!
Next one coming this weekend ;)
Fantastic, this is superb.
Keep on the good work @Jeremy
Thank you :)
Awesome!! really love it :)
I commented in the VLSM video about using route aggregation (though I couldn't remember what it was called at the time) using RIP v1 you could use VLSM with route aggregation. I am sure the reason you don't mention it is because its either out the scope of the CCNA or route aggregation isn't used in the real world.
God bless you ...sir..
Thank you :)
Thank you so much :D
My pleasure :)
After your explanation of wildcard masks @ 29:08 in the video, did the network statement for the 172.16.1.0 network required to have a wildcard mask? If you had a network statement of 'network 172.16.1.0' wouldn't it default to a /16 network which would then include the ip address on the g2/0 interface on R1?
So I get how wildcard masks work and you explained it well.
But what is the PURPOSE of the inversion? WHY is the subnet mask converted? It just seems so unnecessary but maybe I'm missing or misunderstanding the crux of it
Sir, at 15:30 gateway last resort is set to 10.0.34.1....if both 10.0.34.1 & 10.0.24.1 is treated equally in RIP...why is 10.0.34.1 choose over 10.0.24.1 ???
Exactly, I thought the same
Is Eigrp in the New ccna 200 301?
It's not listed in the exam topics, but you should know the basics outlined in this video.
Hey. There is a simple trick for Wildcard Mask :
Each decimal value (byte) of the result of
(eigrp network + wildcard mask)
Must be
>= greatest corresponding decimal value of any interface IP address set in router
AND
Hello ! I've watched from Day 1 to 25. Now, these topics are not very urgent for my current needs for networking (I don't have multiple paths!), I'm thinking of picking up from Day 30 (and watch the skipped videos later when I have more time) Are the topics in-between needed for understanding Day 30 and on ?
Just a short question regarding minute 7 of this video. You say there that 10.1.1.0/24 will become class A address so assumed to be /8. (10.0.0.0). Based on the logic of the following ones for RIPv1 should not this be assumed as /24 as it is ? so should not it remain a /24 ? Sorry if it's a stupid question!
No, /24 is for class C addresses. 10.1.1.0 is class A.
Hey Jeremy! How many videos yet you're gonna Upload ? I've scheduled to finish Day 24 within two weeks, yesterday and today you're uploading a new one.
I think the course is about 50% finished, so maybe 50 days/100 videos in total.
Wild card masks perfect…I need practice
Starting to feel confident in your subnetting skills? Surprise! Now they are going to invert it. Have fun, or should
I say nuf evaH.
Thanks, excellent video.
Thank you :)
@15:36 I'm a little confused about the "default-information originate" command. Is this necessary? The default route is always in the routing table, so why wouldn't it naturally be advertised to the other routers?
Routers don't normally advertise static routes to their RIP neighbors.
Thank you Jeremy. Thank you,
you are best Jeremy
Do you know if there will be another Boson Exsim and Netsim sale through your link? I am looking for more ways to practice and apply this information. Also are you able to do a video talking about how you have used your CCNA experience? What information have you used the most from your CCNA and CCNP? Hope that's not too much, and as always I appreciate the videos.
When Boson runs their next sale, I'll be sure to let everyone know ;)
Currently I don't have a lot of time to make extra videos outside of the course content, but that's a good idea, I'll definitely make that video in the future :)
day 25. let's goo
Thank you very much! These videos are gems
thanks so much!
quiz 2 got me confused how if I use 0.15.255.255.
way I do it is I take the block size so 172.20.20.17 & 172.26.20.12. so second octet if take block size of 16 to fit both 20&26 in one block so thats subnet of 255.240.0.0 .wild card mask=255.255.255.255-255.240.0.0 = 0.15.255.255.
That would work too, but it's not one of the options!
this video is the hardest,... so far. As a former CCNA, i don´t remember EIGRP was so confusing.,..,,
Hey man thank you for everything.
how many more vidoes will you be making till you finish all the topics that are in the exam?
I'm probably about 50% finished at the moment, so many more videos!
If i need to get the certification soon do you recommend niel's udemy course?
Jeremy, Do you have discount code for the Boson Exams?
Nope! Their summer sale just ended, I'm not sure when the next sale will be.
What’s the point of using a wildcard mask? Why not just use a regular subnet mask for routing?
Hi mister Jeremy amazing tutorial.on QUIZ3 i have some confuse you said correct answer is D, what about option C, thanks in advance
Thanks for your great work J. Please I can’t get the lab and flash card for this video. The last flashcard and lab i downloaded ended on day 24
I update the Google drive every week, follow the same link
It is getting hard! No idea why they invented the wildcard mask...
Wildcard masks have an advantage of not having to be contiguous, so for example you could have a wildcard mask like 0.255.0.255, which matches only the first and third octets. Subnet masks have to be a straight series of 1s followed by 0s, like 255.255.0.0.
Although, for EIGRP and OSPF I don't think you can even do things like that with wildcard masks, at least not in Cisco IOS.
37:28 Wouldn’t a wildcard mask of 63.255.255.255 also suffice?
Q2 in the quiz has left me confused. Even with binary written, still trying to understand the logic of how 128.0.0.0 is a match for 172.x.x.x. Are we not given the subnet mask on the exam for questions like this?
The subnet mask configured on the interfaces is irrelevant for activating ERIGP on them, so it doesn't matter.
128.0.0.0 127.255.255.255 matches both of those addresses because the wildcard mask 127.255.255.255 means only the first bit of the IP address has to match (it's the only bit that is a 0 in the wildcard mask).
The first bit of 128.0.0.0 is a 1.
172.20.20.17 and 172.26.20.12 also have a first bit of 1, so they match the statement 'network 128.0.0.0 127.255.255.255'.
@@JeremysITLab Brilliant! Finally understood. Thanks Jeremy!
@@JeremysITLab so we cannot just take the subnet mask and convert it to wild card mask as you did with 172 network with slash 28 and that wild card mask was 0.0.0.15 so why we didn’t the same here?
@@wafa1203 You can do that if you want, feel free. Although notice that the question doesn't state the subnet mask configured on either of the interfaces, and also none of the answers use a 0.0.0.15 wildcard mask. In quiz questions like this, pick the correct answer from the available options, even if there are other possibilities that maybe correct. When using the 'network' command, there will always be lots of possibilities that will work to activate EIGRP on the interface.
@@JeremysITLab Got it! Thank you!
good explanation
Thanks :)
thank you Jeremy
"yeah, sex is good.
but have you ever received a notification from jeremy's IT Lab uploading a new CCNA video?"
Haha, first time I've gotten that comment!
Hi Jeremy, I have a question here, on your Eigrp lab example, why you put 'no auto summary' command, even it is a classless protocol?
