To echo the well deserved praise you've received from others, you're truly the best Network instructor out there! I've also paid for multiple courses on CCNA but I came cross your youtube when I was trying to get a better grasp on subnetting and your series there really helped me better understand it. I continued my other courses but then found you cover many of the CCNA topics individually, you really help nail things down! I was starting to think this just wasn't for me when I got to the Dynamic Routing Protocols area, but you've really pulled me through. I'm planning on sitting for the exam in the next 2 months, but if you ever developed a structured CCNA or CCNP course, I'd gladly pay for it. Thank you very much for all your work!
I know this is late, but I still wanted to drop a note of appreciation at your kind post. I'm so happy you found my content helpful and it helped push you along in your CCNA & CCNP journey. I hope you were able to pass on your first go! I think about making a full CCNA course pretty frequently, but at this point other projects are taking priority. I'm planning on expanding my Networking series into a full fledged fender agnostic networking course. ANd maybe following that I can branch off into the specific vender certifications. In any case, thanks for the kind note =) GOod luck with your certification goals.
I am close to taking my CCNA, and I am glad i searched through all over youtube about OSPF topic, just like the subnetting this by far is the most "Practical" networking lesson I found, I had watched Neil Anderson, Jeremy's IT, Keith, Cert bros, etc I also read the Cisco official cert book but these are the only videos that nailed it to my brain so far. Thank you Sir.
thank you for your passion and hard work, it's clear you are giving your all to create a robust community here. you're doing a great job, and i sincerely hope it bears fruit for you.
No bull I love it !!! When you are studying for the CCNA, especially if you are just getting into IT from another career, you don't need all of the unnecessary stuff found in other material. I love that this is down to the bone. Great job, I am planning on purchasing your full course. I have been through at least two full paid courses before finding your material and I wish I could take back the hours of pulling my hair out figuring this stuff out because the other courses glossed over things or did not explain them to a depth that I felt I needed. If I ever get to the point of mentoring someone I will send them here first thing. I would love to see a specific CCNA course that actually follows the Cisco Blueprint step by step. A lot of courses try but I think you could do a better job. keep it up!
Hello teacher, thank you for this content. I'm enjoying a lot my journey to study to take my CCNA, I confess that is not easy but it's not impossible either.
literally the best ospf lesson i ever seen till now, thanks i wanted to refresh my knowledge and your videos are the best, i wish i learned from your videos from the start so easy to understand.. thank you so much :)
It’s not just a plain pdf sheet. These animated arrows and underlined items makes it much easier to follow the explanation. It must be hard work to animate that all properly 😅 As a video editor who is learning for CCNA I really appreciate this all. 🧐🥰🫶🤝
Glad you enjoyed this. Yes animation took a bit, but I think it really helps the teaching process. What kind of video editing do you do? Have you done course/education video projects?
@@PracticalNetworking huhaa its just username which is in French. But really iam Tamil. with you Bombal session abt TLS indeed good video and seen ur free of two TLS playlist modules on your channel which i got more into that and likely first week of next month, i will go with your full Course. Believe it should enhance my knowledge abt TLS. Thks
Nice You could mention (even though DR/BDR are not explained in detail) that *2Way* state is correct with non-DR routers, so not 100% relations are expected to be *Full*
Funny you should mention it. I just finished the video which focuses on DR/BDR and the 2-WAY/Drother adjacency state is directly covered =). Hoping to release the next set of OSPF videos in the next few weeks. Find me on Discord if you want to preview that video =), I can set something up.
Brooo i loved your presentation and way of explanation and it's awesome really thank you veryyy muchh. Can you please explain us for BGP also we really need your support.
Glad you enjoyed these, Rasheed. For EIGRP, check out these articles: www.practicalnetworking.net/stand-alone/eigrp-terminology/ www.practicalnetworking.net/stand-alone/eigrp-metric/ www.practicalnetworking.net/stand-alone/eigrp-feasibility-condition/
Awesome contents really ! I have some questions so: When does the router learn about the IP of the peer (seen in neighbor table) ? I dont properly get the DBD packets exchange in the EXSTATE neither : these DBD packet are unicast or still multicast ? Thx a lot !👍
Hi Sir. Thank you so much for the great tutorials. I'm currently on my CCNP journey and these video series helped a lot. Again Thank you very much. May I also ask if EIGRP videos will take place in the near future.
Videos? Probably not. But I did publish some EIGRP articles if that is of interest to you: EIGRP Explained : www.practicalnetworking.net/stand-alone/eigrp-terminology/ EIGRP Metric : www.practicalnetworking.net/stand-alone/eigrp-metric/ EIGRP Feasibility Condition: www.practicalnetworking.net/stand-alone/eigrp-feasibility-condition/ Glad you've enjoyed the OSPF videos =) Good luck with your CCNP!
Not necessarily... not every time at least. Consider if the master has more routes it learned from the slave, it will take longer to "load" them into the LSDB, and therefore will be later to reach the "Full" state. But it could easily have gone the other way around.
Hello and once again thanks for the amazing work. I have a small question though, does the Master/Slave election only maters inside the ExStart and Exchange states ? or does it dictate who start the "LSR-LSU-LSAck" process in the Loading state? many thanks
Hi Ed, At the 2-Way State, will the routers be negotiating (auto) or they are simply comparing configurations (as set by the administrator) to ensure adjacency?
Great question. It's more simply comparing items in the Hello packets. If there is a mismatch, the adjacency fails. There isn't a "negotiation", more like an "ultimatum". (if I misunderstood your Q, please feel free to ask again!)
Hello, distinguished teacher... I want to ask about the empty DBD package that the master and slave exchange during the exchange stage... Do we consider it as an acknowledgment from them of receiving the database summary??.... And is the concept of master and slave the same concept the DR & DR Other??
Yes, the DBD packets form a system of acknowledgement. No, they are different than the DR/BDR, see Lesson 6 for info on the DR/BDR. The Master/Slave are only a component of syncing databases, they don't really serve a purpose outside of that.
