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.

[@Wetheuntitled]

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

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.

[@ofsep]

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.

[@justbright3412]

how far are you now

[@FIREfreezerPR]

I am doing the same. But you also have to take notes!

[@markganus1085]

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

[@jzero1579]

Anytime you say "This is probably beyond the CCNA, but..." I know it's going to get good.

[@JeremysITLab]

Gotta include that extra info ;)

[@neoaragon3980]

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

[@ilkkamiinalainen7116]

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.

[@Sudo-d8i]

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!

[@tsuperuser]

One thing about CCNA that I really struggle with is knowing how deep I really need to go. Im not trying to be a network engineer, I want to get any tech job and work towards SOC analyst. The Cisco exam topic for FHRP is " describe the purpose of FHRP" but then I take a Boson Practice exam thats asking "which of the following statements are true regarding FHRP hello messages". I have already been preparing for the CCNA for 10 months and feel like I could spend another year studying and not cover everything. I feel like describe the purpose of FHRP should be super simple and not go into specifics of the protocols.

[@CL-vx1hz]

Stick to the CCNA program on what they ask, Boson exam goes more in depth, but if you can take Boson and pass it, it is likely that you'll pass the CCNA

[@Bowled.]

Bruh don't think too much just go with the flow... cover CCNA in depth even if your goal is towards soc analyst. I am sure these CCNA makes you learn any cybersecurity with ease and you have a deep knowledge how network operates. It will feel like it is taking a lot of time but "Great things take time" :)

Setting aside the "standby 1 preempt" command. Let's say we prioritized R1 with a priority of 200, and R2 with a priority of 50. However, we first configured R2, then R1. Which router will be the active router in this case. If R2 will be the active one as it is configured first, the question is what's the point of setting the priority then?

You mentioned that HSRP can't loadbalance in a single subnet - Is this true? Cisco explains that MHSRP instances can coexist in the same subnet, with only 1 router being active in a group at a time, and you would configure the hosts 50/50 with the VIP of the active router for a group - This probably goes beyond the CCNA, but I don't think what was given was accurate.
