OSPF Configuration & Show Commands - Practical OSPF
Вставка
- Опубліковано 11 лип 2024
- In this video we walk through an OSPF configuration together and I discuss the commands I am using and their effect. All the while showing you the various show commands you would use to validate OSPF's operation on Cisco routers. Below are the commands we'll be using in this live lab demonstration:
Show Commands:
show ip protocols
show ip ospf interface [brief]
show ip ospf neighbors
show ip ospf database
show ip ospf rib [detail]
show ip route [ospf]
Configuration Commands:
router ospf {process ID}
router-id {router-id}
Adding Interfaces to OSPF:
network {network ID} {wildcard mask} area {#}
ip ospf {process ID} area {#}
This is lesson 5 of my OSPF Deep Dive series. The entire series is available here on UA-cam:

Hi, a software developer here. Thanks to your lessons, I've gone from a complete noob in networking to being able to configure our small business's entire office network in the span of a few months. For a video learner like me, this is by far the best learning resource on networking subjects anywhere on the entire internet.
Ed,what you do fo improve the general understanding of networking is TOP-NOTCH. Please dont forget that. Your'e fixing the world. Your'e an absolute savior.
Thanks for the kind words, Scott. Much appreciated
Absolutely blown away by how straightforward and insightful these videos are. Big thanks for sharing!
You're very welcome, glad you've enjoyed this content!
Hi Ed, I hope you're having a great time in Hawai'i 🏝I am learning a lot from your videos. The OSPF AD is 110, EIGRP is 90, RIP is 120, static is 1, and direct interface is 0.
Nailed it ;) Well done, Andy.
And I certainly am =) So nice to be in the ocean again.
And IGRP AD is 100 : )
Best explanation of OSPF on You Tube!
Thanks Ed, i needed a refresher and you explained it well. Appreciate it.
Glad you enjoyed it, Tamil!
This is great!!. You explained in simple terms. Thank you.
I've been watching videos based on networking for many years and I must say that the way Ed explains the things is one of the most effective trainers I've ever seen. In short still descriptive & effective.
Many thanks for entire series...👍
Thank you for the kind words, Alok. Glad you enjoyed this series =)
You are right Alok
Thank you very much for presenting the OSPF Configuration examples so successfully.
You're very welcome, Gokhan. Thank you for supporting the channel.
At 21:30, I really like how you illustrated that the network command is configuring any INTERFACE that meets an address range (or specific address) into an OSPF process, and not necessarily specifying a network to put into OSPF. The fact that you used /16 to group them, but they were still understood to be /24 was a great illustration of that. I had been under the 'common misconception' you alluded to earlier. In fact, I believe that misconception was exactly what I was taught in school. Lol.
Thanks for clearing that up in a practical, visual, way. 👍💯. Your contributions and effort are monumental.
Thank you Scott. Glad you are enjoying this series. The Network statement is one that brought me much confusion, and I've seen many students get tripped up on it as well, so I wanted to speak to it directly. =)
Enjoying is an understatement.....I am loving it
Love the enthusiasm =). Glad you are _loving_ it ;)
This serie is excellent. Best explanation for OSPF. Not tired to watch and watch again. Thank you
Very well explained, could grasp the concept so much better that reading the official cert book...
nice thank you mate im student at TAFE in QLD and your vids are so helpful. it give me a better understanding about OSPF.
This is still another deep dive. Thank you.
Reference point 5:17 in the video; you revealed in your video on OSPF Deep Dive the reason you use process ID '110.' That is the administrative distance value for OSPF.
Bingo ! =)
Excellent work, I've watched multiple videos that goes into ospf , but yours is the most straightforward, practical tutorial series I could find.
Thanks for the kind words, Praveen. Glad you enjoyed this series!
Hello Ed, your videos are definitely the best networking videos I could find on UA-cam. I'm currently preparing for the CCNP ENCOR exam and I have to admit that your OSPF series has helped me a lot so far. Will definitely share and advice your channel to everyone I know in the networking field. Thank you and keep going !
Thank you for your support & the kind words. Good luck with the CCNP !
You are totally right. He is the master; he explains networking concepts in a simple and detailed manner. Waiting for the OSPF network types.
I feel like a beginner so your videos are perfectly explained in detail, wonderful brothers and wonderful channels thanks a lot will recommend my friend that is studying ccna from italy!
Hi Ed, I've followed a few videos over the years but never a complete series. After obtaining the CCNP Data Center I decided to review everything to consolidate the topics. Your explanation of OSPF is absolutely the best online and better than any paid courses I've taken over the years!
I'm still a junior figure in this field (I've been working for almost 3 years) but thanks to studying and your videos my skills continue to grow quickly.
We share the same teaching philosophy: helping others where we have had to struggle to understand things and from your teaching method and attention to detail we understand how much this makes the difference.
Thank you very much, greetings from Italy.
Hi Andrea, I'm thrilled that you've enjoyed this series. Thank you for supporting the channel =) And thank you for the kind words.
Love your videos Ed. Your content and your approach to teaching is amazingly unique. Would love a BGP deep dive series
I've never someone explains OSPF in a similar way you do. Much appreciated and keep it going please :)
Thank you a ton
You're very welcome, AJ. Thanks for the kind words.
Thank you, I’m enjoying this a lot !
All the best man
Hello Ed, your explanation were so cleat that now I can comprend how OSPF work. Thank you!
Great to watch your useful video sessions... because of OSPF AD is 110, you configured the same as OSPF process ID.
Best practical explanation i ever seen ! Congrats !
Would love if you made a "Practical EIGRP", "Practical BGP", "Practical MPLS" series, as well !!!!
😀😀😀😀😀😀😀😀
I bet they would ROCK also !!!
Glad you've enjoyed the series =). You can access all the videos here: pracnet.net/ospf. BGP comes up a lot as a suggestion. I'd be keen to do that =).
As for EIGRP, I've written three articles you might enjoy:
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/
@@PracticalNetworking Yes, i did found them out ! Tomorrow is the day for them ! :)
Again, congrats for your great job !
Thank you very much !
@@christostz03 Cheers, Christos. Hope you enjoy them the way you enjoy this one =).
Very informative demonstration. Thank you.
Excellent , to the point session, helping to gain more knowledge in quick time. Excellently done!!!
Glad you enjoyed it =)
I truly enjoy your teaching style , you are direct and knowledgeable . I am currently studying for my ccna and every time I watch your videos my confidence in networking shoots through the roof . I get why you chose the process id number of 110 because thats the administrative distance for ospf . I will continue to watch your videos and recommend them to my peers . Thank you .
> _every time I watch your videos my confidence in networking shoots through the roof_
This line spoke directly to my heart, it is a large part of why I got into Training. To help alleviate some of the stress and confusion I had when I was first learning networking.
Thank you for the kind comment, I'm thrilled that you have learned so much from this series =).
And yes, you nailed it on OSPF & the 110 process ID. Cheers!
@@PracticalNetworking He's totally right. Your manner of explaining is unique and makes you fully confident (the human version of the happy state XD) of what you're doing. I sent this video to my teacher and he suggested all my classmates to watch your OSPF playlist. Thank you for what you're doing and we're waiting for other series :).
One of the best if not the best free series on yt.
Thank you for the kind words. My goal is for this to be _the_ premiere OSPF resource on YT. =)
pid 110 because of the administrative distance... nice :)
pretty helpful video, i have a test on this tomorrow and completely forgot what i practiced cuz i missed class most days when we covered this. thanks!
Nailed it =)
Great lesson! Your channel is my “Go-To” channel for learning Networking. Thank you!
Awesome, Hector =) Glad you've enjoyed this content. You're very welcome.
Ed, best videos out there. Thank You so much for your efforts!
Fantastic stuff as always. Thanks for all the great explanations
Dude, you videos ROCK! Although I'm using Packet Tracer and some commands like SHOW IP OSPF RIB do not work, I could understand and put it all into practice. Much obliged and keep on keepin' it on!
Awesome, John. Glad you're getting a lot out of this series =). G/L with your OSPF studies!
this is the best network videos.
Hi Ed, I am preparing for my CCNA exam and i came across to your videos for my review. I really like the way you explain things with the detailed information and it helped me understand more clearly. Thank you!
Thank you for the kind words, Riol. Good luck w/ your CCNA =)
If you're willing... Could you do me a favor? Do you mind sharing this video on Linked In, Reddit, Twitter, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ .
I really like this explanation and I learned some new things.
I am really grateful for your free videos ed, I started learning networking after seeing your network fundamentals video, I would have not started a career in networking if I had not seen that, keep making new videos , you are inspiring and changing people's lives
Thank you, Austin. Those are very kind words and it made me smile to read them. I'm glad the videos helped you with your career in Networking =).

Thank you for your work. Excellent!
Amazing content so far !
perfect lesson with excellent explanation
Another gem. Never knew about the RIB command. Thanks as always
Yes, that's a fun one. Love that it shows you the LSA the info was learned from =)
Keep up the good work! great stuff!
Enjoying the series so much...keep it going please thanks
More to come!
Hello Ed, The best OSPF explanation on UA-cam. A Big thank you!!! Appreciate your efforts!!!. Please make videos on Routing and Switching techniques also. Thank you once again.
Thanks for the excellent efforts
btw. I LOVE this course. it resonates so well with me. I had tried some other instructors on youtube but you are thorough and explain the 'why' behind the 'what' perfectly.
I am noticing though that at least on Packet Tracer, the 'rib' subcommand doesn't work on cisco devices.... I'll try it on GNS3. that's what it looks like you're using. the show ip ospf int brief command doesn't seem to work either.
Glad you enjoyed this one too. If you're willing, can you help me share the content among your peers or social media?
Correct, Packet Tracer didn't implement the "rib" command. But you'll find it in real Routers, and on GNS3/EVE-NG, and so on. Cheers, RCHD!
you are a great teacher hats off bro
Both you are amazing thanks a lot for your both efforts
Thank you for your lessons
Excellent video!!!
Thanks a lot , Keep moving and Give the Best.
thank you for your way of explaining things. I should say no word but thank you, you are awsome, and thank you
This is just so much useful. Wow
Extremely grateful 🙏
learning so much. Thank you!
Hi Ed just revisiting OSPF, Also Ive seen your links floating around Reddit, more so than just my own.We are going to show the world how awesome your teach skills are! Great job!
Awesome, thank you! And thank you for the shares I saw a few!
Best ospf Lesson !
Underrated video! Thanks! A new subscriber here
This is awesome. I can see the efforts put in
Thank you for noticing Matt. Glad you enjoyed it.
That is a really good idea to choose process Id 110 same as AD... so can be easily spotted and not confused w any others. I w have to borrow that when building topolgys. Love your interface strategies as well! Thanks for all of your work, it's the best on the 🌐
Thank you for the kind words. Glad you're getting so much out of this content, cheers !
Something worth the watch .Kudos to the efforts .🤜🏻🤛🏻
Cheers, Sakshi!
I enjoyed this video, great and easy understanding video, thanks.
You're welcome !
Great detail, excellent explainatios
Glad you're enjoying this series, Eitan =)
Thanks for your session.
You're very welcome, glad you enjoy it =)
this series is very educational and sexum
Excellent tutorial. Very well explained.
Thank you, Willie. Glad you enjoyed it =)
@PracticalNetworking - Ed, excellent video. I learned a lot. keep up the good work and God bless.
You're welcome! Thank you for supporting the channel =)
@@PracticalNetworking would love to see similar series for BGP and ENCORE
Extremely well explained I ve learned many new things even though I thought that I had enough with OSPF for my CCNA.
Glad this helped =)
Thanks for the valuable information 😊
My pleasure 😊
Just saw this channel. ❤ wow it’s the best
excellent job sir
thank you very much I hope you will make a BGP series
Noted, Hussain. You're welcome!
These are great videos, described methodically and in an orderly fashion. I have learned so much from your videos. Thank you.
PS I couldn’t come up with any reason why you like to use 110 for the process id. :)
Great Job!
Thank you, my dear teacher
- 5:10 Why 110 as process ID?
Since it's the AD for OSPF
- 18:56 routes that begin with letter **zero** .
😂
- 30:24 whether you are enjoying videos so far
Yes, it's very very informative and interesting.
You are the best
Nailed it! And thanks for laughing at the "letter 0" mistake... ha, I caught that in editing.
First thank you for much for the video. The OSPF 110 is the administration distance for OSPF
Thank you so much for your great demonstration for the Ospf topic. I am would like to see topics like SDN and Automation. Thanks again.
You're welcome, Tom. Glad you enjoyed it.
I've been watching videos about CCNP material from Keith Barker and David Bombal. Both of whom are great! However, the way you teach is amazing! I prefer it over their teaching styles. I hope you continue to make videos. I just went on your website as well as added it to my faves. Ill be checking that out. Lots of ccnp individuals are in need of practice labs. Not sure if you do more complicated ones. Keep up the great work!
Thank you for the kind words =). It's an honor to be compared to some of the greats like Keith and David. Noted about CCNP recommendations, maybe in the future !
Informative!
Amazing man 😎
Great explanation..thanks for sharing
YOu're welcome!
thank you - amazing
I like the way you explain all the concepts... The way you teach them, makes more sense to me...
Many thanks 👍
thank you for you didatic! Greetings from brazil
You're welcome! Greetings from Seattle !
Thank you sir!!
Thank you!
A-M-A-Z-I-N-G explanation!!
Thank you, Mr. D =). Glad you enjoyed it!
Cool appliance using 110 as the process ID to match the AD of OSPF.
Bingo!
Thank you so much.
You are awesome. Thanks 😊
You're very welcome, Badr.
Thank you Ed :) Would love to learn BGP deep dive too
well explained
Best. OSPF video
Thank you, Donald =)
bro you are awesome
My guess is that you like to use the Process ID No. 110 coz of OSPF's administrative distance.
Thank you so much for all that you're doing. Greatly appreciated. How I wish you could do Series on EIGRP, BGP and all FHRP Redundancy protocols like HSRP, VRRP, GLBP also Serries on VPN, Etherchannel, Wireless connectivity etc.
Well done
Thank you.
well explained sir.
Thank you, Ankur.
@@PracticalNetworking my pleasure Eddie.
