When the active router fails, Jeremy feels sad, but then the standby router saves the day, and Jeremy feels happy! The standby router saved the day, Jeremy, it saved the day! Look how happy Jeremy is in the top right picture!
I'm praying that God gives you good health so that you continue assisting us
Thank you, Billy :)

Broooo...this might seem like a random comment but I want to state one of the main reasons why you're such a great teacher
@17:25
When you started to explain HSRP with visuals, in my head I was like "ok I think I understand but the visual MAY confuse me more especially with the VLANS but I think I'll be able to understand better if you use different colors...PLEASE USE DIFFERENT COLORS...PLEASE USE DIFFERENT COLORS..." and then BAM! You use another color to bring in VLAN 2 and it helped to glue everything together.
I think a lot of teachers don't understand that PICTURES and colors and moving arrows and packets (lmao) really HELP a lot of folks. People associate colors and pictures etc with kids and think its an insult to their intelligence to learn the way kids learn but idk for me how you just did that helps me sooo much. Thank you very much. Please continue teaching like this. Will be taking my CCNA soon and will then start on CCNP Hopefully this teaching style transfers over to the CCNP videos
I really do like the content. My biggest issue with the CCNA seemes to be that I have to memorize things like mac addresses and multicast addresses for so many different things. In the practical world you would look those things up when needed. This is my only issue with cisco really.
I completely agree. Makes no sense to have to memorize things that you can’t look up in an exam when you can look it up in the real world. Like if they want to include stuff like that. Then allow only a booklet or something to be brought it for that or something
@@Wetheuntitled yeah, it's cisco, they would never allow such things
So many MAC addresses to memorize...
Thank you, Jeremy, for these Anki flashcards.
They really help.
This is to show my appreciation for the super explicit nature of your CCNA videos. Thank you.
Thanks David!
Thank you so much for making it easy for us. By far this is the best CCNA course.
Thank you! And thanks for your support :)
Thank you for making the comment about VLANs being a layer 2 and subnets being layer 3. Learning this information hasn't been particularly difficult via each lesson, VLSMs aside, but putting it all together to make a complete picture has been difficult for me.
Jeremy suffice it to say A thank you is too little to actually tell you how much you have helped all of us watching your videos. You are a great person and a role model. The content of your tutorials are just amazing. I'm just dreaming to become someone like you. Whole hearted thanks to you. Always be blessed.
Thanks for your kind words, Reetesh :)

In my life ive never commented on any teaching video on YT but Jeremy i have to on yours.
Thank you sooooo much for this awesome Videos! I cant describe how easy it is to understand the topics u explain, even for me
who is an german student with low to medium english skills. That says a lot about you as a teacher.
Again thank you soooooo much!!!!
You are by far the best and clearest instructor out there Jeremy Thank You!!
Congrats 🎉 nearing 100 k subscribers. Hard and dedicated work never fails.💖
Thank you! I think it'll be about a week until I get 100k. Thanks to all of the subscribers like you for your support!
Thanks for providing the best CCNA course on youtube. Always good pray for you.
Hello Jeremy, great quality video as always. There is just one thing I wanted to add in what you said, it is indeed possible to load balance in a single VLAN by using HSRP. This can be done by configuring multiple hsrp instances on the router interfaces. Half of the host having the Virtual IP of one instance and the other half using the Virtual IP of the second instance and by configuring the first router to act as active in the first instance and standby on the second instance and inversely for the second router. Thus loadbalancing the trafic across the routers.
hey Jeremy,
this video is awesome as all the ones before this. And I really appreciate the time and effort you've put in to making those video. The way you have broken each part of the video really helps to understand everything. 😀Good luck on your studies too.
Excellent work Jeremy, very easy to understand, bravo and keep up the good work.
Jeremy, Thank you for the course. Please upload course for CCNP, will love to learn.
I appreciate the way you explain each topic . Jeremy, I will pass my ccna and also understand the functions of different protocols and why they are in affect . Thank you again !
You are making it so simple.. Thats amazing.. Again, we have to wait for next sunday for new video. Thank you for your valuable contribution in my career.
Coming in a few days ;)
these kind of updates...
they make my whole week
thanks man :D
you're gonna make me donate a kidney at some point, just to show how grateful i am for this XD
Haha, I'll keep you in mind if I ever need a kidney! ;)
J, dude you still the man. Thanks
Thanks Glenn, good to hear from you ;)
Hi Jeremy, From the bottom of my heart thank you.
It's my pleasure Frank, thanks for watching :)
I'm going to pass the CCNA exam by using this course and intently watching this whole playlist all the way through
how far are you now
I am doing the same. But you also have to take notes!
i passed it on the 17th december 2022. in addition to Jeremy's playlist, i also watched certbros, David Bombal and Prof Messer. I also took plenty of simulated tests and did a buttload of labs on cisco packet tracer, besides also taking notes and making personalised summaries of everything and using the anki flashcards.
it was relevant for my job back then. but now I work as a data analyst and the only parts that relate to my current position are the lessons at the very end, namely the ones that talk about json, xml, yaml, apis and postman.
i still rewatch the videos and re-read my notes often, if anything for nostalgia's sake. it was an interesting journey, and I will always fondly remember every moment of it
I am thankful and grateful for your job ❤️
GOOD LESSON JEREMY!!!
Excelent explanation, thank you very much Jeremy. Regards from Costa Rica.
Thanks Andrey :)
Just went through your after a long time and it was smooth explaination thanks
You are the Dude! Dude! :) I really really love your work and beeing very grateful to you
Thanks dude! I appreciate your support :)

You are simple awesome Jeremy. Thank you.
You're awesome! ;)
To configure an HSRP virtual IP address, the command is:
router(config-if)#standby [group-number] ip [ip-address]
Note: If the group-number is not entered, then it will default to a group number of 0.
The ip-address parameter does not necessarily need to be included when configuring all HSRP interfaces but it DOES need to be entered on at least one HSRP device. The other devices are able to learn the virtual IP address from this device.
i.e R1 command would be R1(config-if)#standby [group-number] ip [ip-address]
and R2 command can be R2(config-if)#standby [group-number] ip
very good lecture, many thanks
Thank you so much Jeremy
i don't even know why i'm so happy when he says that, even if it's not in the exam topic list, we'll still get to see basic configuration xD
I like networking and it's thanks to you man !

Your explanation is really fantastic in very detail ...I am hoping that you would be my trainer for BGP and QOS topic as well someday
After the CCNA course, I will cover other topics for sure ;)
Best lesson
Just wow ❤
Thank you so much
Thanks for watching :)
Thank you for these great videos. Could you please share some troubleshooting videos which can help in interview.
Maybe in the future! Focusing on this course, for now.
Hi Jeremy. You r smart
Thanks❤❤
Thank you Jeremy will you be covering IPv6 in the coming videos
I will cover all CCNA exam topics.
@@JeremysITLab Thanks Jeremy
Great explanation, thank you. Quick question: which one of these FHRPs is used mostly in the industry?
Probably HSRP for Cisco devices, VRRP for non-Cisco devices.
Practically I find this specific concept a very "nieche" portion of the whole CCNA. Personally I would only "memorize" the IP addresses, and simply be able to recognize the mac addresses. From what I have gathered from others also support this. No need to learn every single nieche topic on the CCNA level, however if you are planning to go CCNP or beyond, one probably ought to learn this by heart.
Finally 😍😍😍
Sorry for the wait ;)
35:30 make like a router and choose the most specific option. lol.
Man, as I keep getting further and further in the views keep dropping. Don't worry, you'll have more views from me!!
3:38 this feels very much like the adult life version of Dora the Explorer, where the questions are actually hard to answer. I feel you kids.
Jeremy 2024!
Yeah! What office am I running for??
These are use for exhanging hello messages between routers in the same fhrp group.
Active- ipv4 address & virtual shared mac address
Standby- ipv4 address & mac address/bia
Hello Jeremy, Thank you for the video. Really informative and clear to understand. What is the difference between v1&v2 for HSRP? Thank you
14:42 'Version 2 adds IPv6 support and increases the number of groups that can be configured'
@@JeremysITLab My bad sorry. thank you for the response. Appreciate it.
16x16 is hexadecimal 100, anything less than that has two digits, first on is a number of 16-ins (in hexdec), and second is reminder
Thanks, Jeremy
Thanks for watching, Stephen :)
new thumbnails nice
Thanks! Working on updating them all
We need your knowledge man.
Thanks for the video Jeremy!
Thanks for watching, Nicholas :)
Hi Jeremy thank you for another great lesson. The last digits of virtual MAC address (all protocols) must always to be converted in hex correct? (in case from 0 to 9 are simply the same)
Yeah that's correct, MAC addresses are always written in hexadecimal so you'll have to convert to hex.
Hi Jeremy, Thanks a lot for your videos. I have a Question. Could you please tell me what happens when data wants to enter a network with HSRP? Will it be sent to the Active router? to the Backup router? or both? I wish you could explain...
Hey Jeremy, I was unable to find your content on the states of HSRP, would the exam include those questions?
Awesome and well explained. Thanks. While the underlying system is clear to me i wonder how long i'll take to learn the MAC addresses, even with the Anki flashcards, i jsut have issues learning those addresses without any kind of "logic" behind them that i can grasp.
Write them down over and over again, it helps with inane information like that that you just need for a test and end up forgetting it immediately a week later.
Hi Jeremy! I tried HSRP with 4331 routers on CPT. Even if there is no preemption, higher IP address owner router becomes active after shutting down and coming back online.
The virtual mac address is the same for the active and passive router ?? Because I thought if it yes, possibly in this scenario occurs mac address flapping where the switches record the same mac-address with different interface destination.
thank you for this great video , i just have one question does GLBP can load-balance also per subnet like HSRP & VRRP and for each subnet can elect AVG and 4 other AVF ?
like if there is 2 groups of GLBP in each group will be 1 AVG and 4 AVF that means in total there is 2 AVG and 8 AVF
Yes that's correct, if you configure multiple GLBP groups, each group can have different AVG/AVFs.
Thank you very very very much.
Actually I have a suggestion: woud you please do a video to show how to configure a second ISP internet router which has different subnet as failover router.
Example: Primary router IP is 213.0.113.1 and failover router IP is 196.0.113.1
Looks like no one FHRP could do it.
I crawled the web but couldn't find smthg working. Honestly it's beyond my current knowledge.
Thank you very much!
newer version of CCNA doesnt include beyond hrrp. btw, your videos is awesome
3.5 Describe the purpose of first hop redundancy protocol
^Seems pretty general, not just HSRP
Hi Jeremy !! Thank you so much for your videos .
I want to ask you a question that is not about this lesson but a question in general.
What is Packet Switching ?
It's just a word for the process used to send data (in packets) through a network to a destination.
Here's a definition from Wikipedia: 'The routing and transferring of data by means of addressed packets so that a channel is occupied during the transmission of the packet only, and upon completion of the transmission the channel is made available for the transfer of other traffic'
Is the Virtual Mac Address the same for both routers?
גאון
Bro this course is very simple and very helpful . But some times i didn't get the video orderly . So if you can , can you make this whole video as a single video? That would be very helpful........
I recommend using the playlist: czcams.com/play/PLxbwE86jKRgMpuZuLBivzlM8s2Dk5lXBQ.html
Hi Jeremy,
Can vlan consists of devices with more than one subnets (and vice versa) ? If yes, please elaborate.
Are the following statement true ?
Each subnet will have one and only one broadcast domain (all host bit to one).
A vlan consists of devices which have same broadcast domain.
Hello Jeremy, you are doing a great job! Thank you for all those videos. I have a question. If PC1 is connected to SW1, and SW1 is connected on R1 (VLAN10). Then we got a PC2 connected to SW2 connected to R1 (VLAN 20) - Same router. The R1 has G0/0 connected to SW1 and G0/2 connected to SW2. Both switches are connected. I understand that there need to be trunks between SW1 -> R1 SW2 -> R1 and SW1-SW2. Also, the ROAS needs to be configured on the router. The problem is that when creating an ROAS on the router. I noticed that the encapsulation dot1Q (VLAN) can only be configured on one interface. What happens if that interface fails?How will the route reach another interface? The encapsulation for a specific VLAN/IP can be configured on one interface.
This is not a realistic network topology. When using an FHRP the point is to provide redundancy, however if you're using just a single router that redundancy is lost, as the router is a single point of failure.
Question: since the gratuitous ARP is broadcast, what happens when the PCs aren't in the same subnet? It would reach only the switches within the same subnet, but they won't go beyond that. How does it update the PCs then?
15:44 Remember
