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.
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.
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.
You questioned why I use Router ospf process ID 110. The answer is that it resets the ospf ad value, which makes it interesting since most of the time people forget what the ospf ad value is. By utilising this ad value, you are providing information about the administrative distance of the ospf.
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...👍
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. =)
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.
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 :).
Hello Ed, your videos are definitely the best networking videos I could find on RUclips. 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 !
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.
- 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
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 =). 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_ .
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_ .
Hi Ed, you're doing a great job here. There's no presentation like this to fully understand OSPF. And to answer the question why you put process ID of 110 - the number you chose is actually the administrative distance oof the OSPF itself. This show how reliable the protocol is. For example: if a router receives a route to a specific destinations from let's say OSPF (AD110) and IGRP (AD100) the router will choose IGRP because it is more reliable, it has lower administrative distance
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!
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.
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!
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!
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!
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 🌐
Hello Ed, The best OSPF explanation on RUclips. A Big thank you!!! Appreciate your efforts!!!. Please make videos on Routing and Switching techniques also. Thank you once again.
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 !
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.
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/
Hi. Great content. Maybe it make sense to make a short video about ospf redistr connected vs passive interface default . Please keep this gold content comming !
Great suggestion! I don't think I had added passive interfaces to my list, but 100% that is necessary for this series. I'll include a demo of redistributed connected when I get in to type 4 and 5 LSAs later in this series. =) Glad you're enjoying it. _(If you are willing, please help me spread the word about this content, thank you)_
Hello Ed, i hope you are having a great time. your videos really helped me a lot. the think that i want to know is what is the programs that you are using when configuring the routers? i saw on the is says putty but how? thank you very much
thank you for your hard work Just one question I tried to follow you and do every thing identical to your topology and configurations but i noticed some differences in show commands like show ip route (yours ospf networks are /24, but mine /32) show ip ospf interface br (yours state in command is p2p, mine state is loop) Did I do any mistake here ?
Great job following along. No, you didn't do anything wrong. In the demo I set up the Loopbacks as point to points so they are advertised as /24s instead of /32s. At this point in the series (lesson 5) I didn't want to go into the details of network types, so I didn't show that part. Maybe I should have. In any case, I unpack the details of Loopbacks and Point to Point in the Network TYpes lesson =)
Thank U sir🙏... Love Ur work. I was struggling to keep up with my online classes, as I missed some of them. Ur videos helped quite a lot. Now I have a clear idea of what's happening inside OSPF. 🙏🙏🙏🙏 Also can U do a video on routing redistribution.?
Hey buddy, another great video. Thanks! I do have a question. When you entered loopback interfaces on router 2 using the network command, were those loop interfaces already configured on router 2? How did r 2 know to make them loop intfs? When you did the config on r 1 in intf config mode, that was simple for me. But the first method on r 2 was a bit trivial to me. Thanks!
Glad you enjoyed it, Sean. Yes, the loopbacks were already configured. If they weren't, the Network command wouldn't have done anything. The Network command looks at whatever active interfaces are configured on the device, and enables them into OSPF _if_ they match the IP/Mask provided in the network command. Hope this helps. IF you have more questions, feel free to pop in on Discord: pracnet.net/discord
@@PracticalNetworking Okay, it's more clear now. I thought the loopbacks were already configured but I wanted to hear it from you, from the man! :) Thanks and take care!
There are always only *one* Type 1 LSA for each Router, regardless the number of links/connections. For every non P2P connection though, there will also be an _additional_ Type 2 LSA, pointing towards the DR for that link. HTH
Hi, awesome explanation of each command. Small query, when we are using command sh ip ospf interface , getting P2P in state section for loopback but for ethernet we received DR . Please explain why we received P2P for looback interfaces.
I wasn't ready to talk about network types in this video, so I set the network type on the loopback interfaces as Point to Point w/o explicitly explaining it. I discuss Point to Point and Loopback interfaces in my TYpe 1 and TYpe 2 LSA video: ruclips.net/video/1FOBkIoDbCc/видео.html You might also enjoy the DR/BDR video: ruclips.net/video/Mi3tNSUjb78/видео.html Or the whole OSPF series: pracnet.net/ospf
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. :)
There isn't... Packet Tracer doesn't implement the full router feature set. There are some commands in the video I use that won't exist in packet tracer =/ You'd have to use GNS3 or EveNG or VIRL/CML to replicate this lab.
is this the same for XR or XE? I know where I used to add routing into interfaces in XE it is now you add the interface to the protocol in XR 110 - default distance for OSPF
Hi Ed. Thanks for your amazing videos. I learn a lot from them. I have a question: How do I practice all this. I know I need a practice lab, but the problem is that I can't afford one. So, I was wondering if there is a free online lab?
Great video and tutorial indeed, and I have seen a few :) I noticed that you did not have to specify "ip ospf network point-to-point" command to get you loopback to show as "p2p" and you had those networks advertised as "/24" and not "/32" as my did. My loopbacks showed as "loop" until I ran the command above...
You caught me ;). I intentionally left that out of the video to avoid getting into the different network types (there will be another video for that). But despite that, glad you enjoyed it. And yes, Loopbacks are by default considered /32 "networks" in OSPF, if not for the `ip ospf network point-to-point` command.
@@PracticalNetworking Thanks a lot for confirmation, for a sec there, I thought it might be the difference in cisco images 🙂 Anywho, I really enjoyed this and all of your tutorials 👍
when you advertized all the routes and did show ip ospf database both routers were showing the same type 2 entry for r1 why though i thought it will r1 will show of r2 and vice versa.

Great to watch your useful video sessions... because of OSPF AD is 110, you configured the same as OSPF process ID.
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!

The 110 that you are using for the OSPF process id is the OSFP routes default admin distance.

Just one question
I tried to follow you and do every thing identical to your topology and configurations
but i noticed some differences in show commands like
show ip route (yours ospf networks are /24, but mine /32)
show ip ospf interface br (yours state in command is p2p, mine state is loop)

At this point in the series (lesson 5) I didn't want to go into the details of network types, so I didn't show that part. Maybe I should have.
In any case, I unpack the details of Loopbacks and Point to Point in the Network TYpes lesson =)
Thank U sir🙏...
Love Ur work. I was struggling to keep up with my online classes, as I missed some of them. Ur videos helped quite a lot.
Now I have a clear idea of what's happening inside OSPF. 🙏🙏🙏🙏
Also can U do a video on routing redistribution.?
Glad you've enjoyed this content! Redistribution is on my list to cover. Cheers !
@@PracticalNetworking Thank you🙏💕
Hi why didn't we introduce WAIT state in previous video? thanks.
WAIT is an _interface_ state, not a neighbor adjacency state =).
Glad you are enjoying the series.
Hey buddy, another great video. Thanks! I do have a question. When you entered loopback interfaces on router 2 using the network command, were those loop interfaces already configured on router 2? How did r 2 know to make them loop intfs? When you did the config on r 1 in intf config mode, that was simple for me. But the first method on r 2 was a bit trivial to me. Thanks!
Glad you enjoyed it, Sean.
Yes, the loopbacks were already configured. If they weren't, the Network command wouldn't have done anything.
The Network command looks at whatever active interfaces are configured on the device, and enables them into OSPF _if_ they match the IP/Mask provided in the network command.
Hope this helps. IF you have more questions, feel free to pop in on Discord: pracnet.net/discord
@@PracticalNetworking Okay, it's more clear now. I thought the loopbacks were already configured but I wanted to hear it from you, from the man! :) Thanks and take care!
@@seanknight9808 Cheers Sean. Glad it makes sense now.
Both you are amazing thanks a lot for your both efforts
Ed, If you have 2 links between router 1 and router 2, how many Type 2 LSAs are advertised from each router?
There are always only *one* Type 1 LSA for each Router, regardless the number of links/connections.
For every non P2P connection though, there will also be an _additional_ Type 2 LSA, pointing towards the DR for that link.
HTH
Hi, awesome explanation of each command. Small query, when we are using command sh ip ospf interface , getting P2P in state section for loopback but for ethernet we received DR . Please explain why we received P2P for looback interfaces.
I wasn't ready to talk about network types in this video, so I set the network type on the loopback interfaces as Point to Point w/o explicitly explaining it.
I discuss Point to Point and Loopback interfaces in my TYpe 1 and TYpe 2 LSA video: ruclips.net/video/1FOBkIoDbCc/видео.html

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. :)
Underrated video! Thanks! A new subscriber here
Thanks a lot , Keep moving and Give the Best.
thank you for you didatic! Greetings from brazil
You're welcome! Greetings from Seattle !
Thank you for your work. Excellent!
this series is very educational and sexum
Amazing content so far !
Thanks for the valuable information 😊
My pleasure 😊
Hi Ed, by any chance, is there a packet tracer for the lab? thank you
There isn't... Packet Tracer doesn't implement the full router feature set. There are some commands in the video I use that won't exist in packet tracer =/ You'd have to use GNS3 or EveNG or VIRL/CML to replicate this lab.
110 is the AD value of OSPF
Bingo =)
is this the same for XR or XE? I know where I used to add routing into interfaces in XE it is now you add the interface to the protocol in XR
110 - default distance for OSPF
Hi Ed. Thanks for your amazing videos. I learn a lot from them. I have a question: How do I practice all this. I know I need a practice lab, but the problem is that I can't afford one. So, I was wondering if there is a free online lab?
Extremely grateful 🙏
Great video and tutorial indeed, and I have seen a few :) I noticed that you did not have to specify "ip ospf network point-to-point" command to get you loopback to show as "p2p" and you had those networks advertised as "/24" and not "/32" as my did. My loopbacks showed as "loop" until I ran the command above...
You caught me ;). I intentionally left that out of the video to avoid getting into the different network types (there will be another video for that).
But despite that, glad you enjoyed it. And yes, Loopbacks are by default considered /32 "networks" in OSPF, if not for the `ip ospf network point-to-point` command.
@@PracticalNetworking Thanks a lot for confirmation, for a sec there, I thought it might be the difference in cisco images 🙂 Anywho, I really enjoyed this and all of your tutorials 👍
when you advertized all the routes and did show ip ospf database both routers were showing the same type 2 entry for r1 why though i thought it will r1 will show of r2 and vice versa.
Best ospf Lesson !
This is just so much useful. Wow
Thanks for your session.
You're very welcome, glad you enjoy it =)
