INE Live Webinar: Understanding OSPF LSAs

[@eugenealejandro8627]

Mr. Legendary right there. Salute to you Keith! In all fairness, "Keiths" are born legends!!

[@cycleof7s438]

Ain't that the truth. I'm almost half way through and I have filled in so many learning gaps in the past half hour watching this than I have in the past 5 years learning OSPF. He explains things in a way that while he brings you along, he breaks things down into segments and each segment flows into the following to where you are left with little to no questions/doubts. Bogart is simply the man.

[@JIKID]

FANTASTIC lecture Keith! Thank you so much for it. I watched the entire thing and got so many gold nuggets from this!! 🙏

[@mathelize]

Well done Keith. You explained this very well! I've understood it now.

[@ferozsyed2014]

Another best Instructor from INE.

[@EvaSlayAllDay334]

It might sound ridiculous, but I like it dumbed down. I like it simple and understanding logically what the purpose is for protocols, services, etc. Keep it straight-forward without the fancy fluff terms.

[@arifpatel8944]

The method and technique to teach and train through fundamental and concepts of protocols is Amazing and Exceptional with Excellence.... Thank you so much, Keith for your great Efforts.....

[@piyushsaini8453]

It's just WOW....... superb explanation 👌👌

[@ospfv6version_331]

I very appreciate your explanation of Link state types ,greate instructor ,many thanks to your efforts

[@rainbowadventures4638]

WoW. This is great video..I have never seen anybody going to this depth! Thank you so much

[@tahersadeghi6773]

Thank you for a clear explanation.

[@mountainscott5274]

at 34:46 does anyone know to which router 22.22.22.1 belongs? It's not present in the topology from what I see. [edit] Okay now I see the topology has a typo. The interface facing R2 on CSR2 should be 22.22.22.1 not 22.22.22.22.

[@lkdipeolu]

Thanks. You did a marvelous Job on LSA type description. I love it. I will definitely remember you for this.

[@zorlac72]

Master Keith is the best of the best! Thank you! 🙏

[@rikaettal4535]

so far the best explanation you can find out there. this is great and very good done. Thank you so much for sharing.

[@networkengineer2734]

Thank god,got just what i was looking for

[@mc-wi8wp]

Thank you. I am preparing for a Juniper certification, but since this is vendor neutral, it helps me a lot, so thanks.

[@cooptars7338]

Great and simplified explanations ... thanks so much Sir

[@blendonator]

I really enjoyed this one, Keith. Thanks! I always had a hard time remembering 1/2/3/4/5 types, but the diagrams helped tremendously. Still a rediculous routing protocol with NSSA/Totally NSSA etc, but this was half the battle 😝

[@ac1927]

Really great explanation, for such a tricky subject such a easy and straightforward explanation... Really well done!

[@amirekhalili]

Thanks Keith for your ultra powerful explanation.

[@pcpmtiservicos9855]

Thank you very much for the quality of the content Keith, congratulations for your way to explain such detailed processes

[@shaktishakti991]

Great Video Sir, Thanks you

[@uttherkunst3806]

Thank you, this is absolutely excellent.

[@sushantjoshi7030]

this guy explained OSPF LSA TYPES better than Brian

[@semtex6412]

great video lessons as always! can't thank you enough, Keith! just a quick one, tho. on 24:14 - (re. LSA MAX AGE), the lsa from R2's link to R1's G0/2 has already reached the 1800th mark (1821 to be exact), but it looks like it hasn't been purged and is still on sequence "2A". what happened there? was the max age explicitly configured? i would really love to know Sir.

[@mojdomu4883]

That's a cool LSA workshop which explains the roles of LSAs in a great detail. I believe, this webinar is helpful for anyone who needs to clear some confusions. Do you provide CCDE bootcamp on INE or do you have such plan for the future Kevin ? I am really interested in this program after passing CCIE exam.

[@chetanchaudhari1011]

Great .. very nice video.. Could you please make video on OSPF backbone area 0.. why it is use .. and why it necessary to all ospf area routes should go via area 0.. Thanks

[@prashantshinde5318]

how do we reduce type 4 lsa translations

[@saadahmed4748]

I appreciated your efforts Keith, I need E-2, E-1, N-1 & N-2 difference video stuff

[@cdyz5]

dam it is a good video. Thank you Sir.

[@IFBBPro]

Great video.

[@juanserna3282]

One question, the videos for course of cisco it with english subtitles? I have intermedias english and I help myself with the subtitles.

[@tkhue3296]

When we connect 2 routers via serial link and configure as P2P network type, there will be 2 entries in the LSA type 1, one entry is point-to-point and another is stub network. Even though we have only 1 physical serial link but we get 2 links count, We have OSPF neighbor the other end but it is considered as sutb network, this is really confusing.

[@BoltThrower321]

Yep, Mr. Bogart knows his stuff. Only thing I miss is an overview what is really needed for labs...exspecially with the new Enterprise exam

[@alexribas2010]

You rock, very good video.

[@rAndOmNeSs26]

Thabk you

[@rainbowadventures4638]

Are Type 1/2/3 LSA received by 1 Router forwarded forward to another Router? If CSR1 and CSR 2 in Area 51 were DRs advertising their respective networks, how do they learn about each other's networks if BDRs were not forwarding them back and forth?

[@networkgeek5091]

Hey Keith,Thanks for the tutorial although I understood the mechanism of LSA you explained, but still struggling with this that y Area 51 needs type 4, Type 1 LSA and Type 2 LSA are combined to build Type 3 ,Type 3 are advertised by CSR1 to Area 51,Then by this logic Area 51 should know how to reach ASBR

[@networkgeek5091]

or is this the case where CSR2 in Area51 doesn't know the router which is generating type 5(but it knows sw2 from type 3... and it's the same who is sending type5) and type 4 act as a lookup for type 5 generating router?

[@EvaSlayAllDay334]

OSPF Area 51...I saw what you did there :)
