I truly enjoy these videos, even though i know this stuff already by heart. But i am always fascinated by the simplicity with which Keith can explain even the most complicated technologies and his enthusiasm. One can hear and see how much he enjoys his work, if you can even call it work in his case, it looks more like pure pleasure.

i gotta say, i keep getting discouraged with this networking path every time i stumble on a subject or get a trash score on a practice test, but seeing your dedication and passion in this keeps me motivated. extremely good at breaking subjects down into easily understood pieces; i feel like one could even get a better grip on how to teach people simply by watching you. thanks a ton for going through the effort of putting this content together. EDIT: I ended up successfully passing my CCNA, in big part because of your content. Thank you a ton. I will almost certainly be referencing back to this stuff as I get my bearings. The fact that you put this stuff up for free is a blessing, and you're awesome for it. thank you.

Hey Keith! Got a question i been working with ipv6 ospf inside packet tracer and i have neighbor relationships between all my routers but on some routers have no ospf learn routes. Thus they are unable to send packets across my network. Isn't weird that they have a relationship but they are not sharing routes or LSAs? Could this be a packet tracer error or am i missing something? All my interfaces are up and for references my network is setup exactly like your TCP/IP IPv6 class on CBT nuggets video 10.

Going back to watch all 4 of your videos on OSPF! I just completed this entire OSPF section in the new CCNA course you did, so much stuff to mentally digest, oh boy. However, I think I need clarity in understanding a few things better and I think it's just better to watch all 4 the videos you have on OSPF specifically in order entirely. I also had a really hard time trying to understand "loopback Addresses" and what's the point of them. I'm thinking it seems like an ID, yet it seems all fuzzy to me the whole thing. I figure, just go over all 4 your vids.

Keith , do you have to create a router id , when configuring OSPF , on your example you didn't do it , or is it an optional command . thanks
@KeithBarker
@KeithBarker 4 жыл бұрын
Thank you for the question Manuel. The OSPF routing process needs an ID. When the process is started, here are the 3 options it has, in order of preference, to select a router ID. 1 a configured router ID in the router process of ospf 2 a loopback interface that has an IPv4 address on it, when ospf starts 3 a normal (non-loopback) interface that has an IPv4 address on it, when ospf starts So in short, if I didn't specify and OSPF router ID, it would then use option 2, and if there weren't any loopbacks, it would use option 3. Hope that helps, and thank you for watching.

Hello Mr Kheith I can’t find words to thank u. I’m watching your video for about 5 years. thanks to u and to God , I’m CCNP Routing and Switching. Now I’m working as a networking Engineer and your design is seemly like my topology. But rather than using a routers to access internet I’ll use Cisco ASA in front.I’m not so good with firewalls. My question is : It’s will be possible to these Firewalls (active/active) to participate in ospf process and each Firewall will be active to some subnets et standby for the other subnets. In my opinion the implementation will be standalone with the same configuration. Thanks

@KeithBarker
@KeithBarker 2 жыл бұрын
Thank you José Andrés López! A router can run multiple instances of OSPF, just like a smart phone can run multiple apps. Most of the time, routers only need to run a single instance of OSPF. The process ID is how the local router tracks that instance of OSPF. Because the process ID is locally significant, it does NOT have to match the process ID of another router. This is different than EIGRP, where the Autonomous System number on both routers need to match in order for them to become EIGRP neighbors. Feel free to join my Discord sever. Lots of people there helping each other out. Each Saturday at 10am Pacific I hold my "Office Hour" where learners can ask questions about the topics they are studying. Mostly focusing on Cisco CCNA 200-301 topics. Feel free to join us there live if you are available. Here is the link ogit.online/Join_OGIT_on_Discord Thanks again José Andrés López!

Sir in ospf at least one area should be there for forming adjacency right? Without area ospf will not work right? Area 0 is backbone area, I know that. If suppose two router's are there both interfaces facing each other in( area 0 or area 1) it will become neighbors right. Without area there is no concept of ospf. I asking these questions because one interviewer asked me 'without area is ospf will work or not'?
@KeithBarker
@KeithBarker 4 жыл бұрын
Thank you Sreejith. Imagine two routers, connected to the same network segment (same VLAN, IP network). They must agree regarding that common network, which area that network is assigned to. If they don't agree, they won't become neighbors. Here is a short list of what much match to become neighbors, they must agree on: IP network/mask - Area # - Timers - Whether or not a DR is going to be used. (Broadcast and Non-Broadcast OSPF network types are the only two that expect to use a DR on the segment). Authentication (if it is used or not, and if so what type, and if so what password is used) OSPF requires an area. In a single area, that area should be area 0 or sometimes 0.0.0.0 (both mean area 0) If there is a single area, and a different number is used, such as area 9, it will still function (this is not best practice, and rarely done other than a test or demonstration). Thanks for the questions, and best wishes to you!

OSPF Implementation question, best practice? L3 switch with a bunch of SVI's and couple of OSPF Neighbors via L3 switch port on the same switch. With use of proper passive and active interface commands under the OSPF router process to prevent the SVI from joining the OSPF neighborship process, is it better and or cleaner to use the network statements or go to each SVI and Interface and use the "ip ospf process area" command to include the associated network in the advertisements? basically ip ospf 1 network 10.10.10.0 0.0.0.255 area 0 vs. interface vlan 100 ip ospf 1 area 0

Thank you for the question Michael Atchinson. If doing it manually one factor is time. If there are dozens of interfaces, more work would be needed compared to network statements. If it is only a few interfaces that will be running OSPF, the interface configuration option works great.

Anyway, you can expand and explain what exactly the "Process ID" is? I didn't quite properly understand "Area" from the CCNA course, but you covered it well here at the beginning and at the end also answering someone else's question both so it helped. As well I picked up a few things I missed as well, so was very helpful.

Thank you for the question. Let's imagine you wanted to open a browser app on your phone. Then a moment later you wanted to open another instance of that same browser. (Have 2 copies (2 processes) running at the same time, not just multiple tabs in one of them). To do that, your phone would need some way of keeping those apps (processes) separately, such as thinking of them as 1 and 2, or A and B. The router is the same way. If OSPF is running on the router, like an app running on the phone, the router keeps track of this app (this OSPF process) via a process ID. It is required to have one. This way, if we ever need to run a second copy of OSPF, it will have a separate process ID, and the router can keep track of them individually. For CCNA you will never need to run a second instance of OSPF at the same time, but the process ID is still required for OSPF even if you are running only 1 instance (copy) of it on the router. Let me know if that helps. :) -Keith

Keith Barker This expanded explanation helps a bit. And since I have 14 browsers open on my phone I can understand that point well. I also found a recent video by David Bombal that gave an interesting point of view on Loopbacks also. Some of it clearly went over my heard being beyond my understanding, but I understood some of it that it also helps after watching it 3-4 times. It was this one: kzfaq.info/get/bejne/psCYopmAtr-9qH0.html

@Keith Barker I’m not sure as yet what a Block Size even is. If you can link it, I’d surely look at it. Unless I can exactly determine just which video that is. Added question. Is OSPF available on a L3 Switch? In that since a L3 Switch operates very much just like a regular Router, is a L3 Switch also capable of OSPF?

Thank you for the question Gaurav. If you are brand new to networking, the CompTIA Network+ is a nice gradual introduction from a vendor neutral perspective. Then, the CCNA will use a lot of that knowledge and build on that with specifics to Cisco. Either way, enjoy the journey and enjoy the videos here on KZfaq. ogit.online/sloth

Hi Keith, I am creating a site to help people train for the CCNP/CCIE 350-401 exam and I want to put a link to this video as a reference. Is that OK? I am new at doing this, so I don't know if I am crossing any copy rights red line or whatever, the internet is crazy these days. I want to also put Cisco's OSPF Configuration website and stuff like that. Thanks for your help.
