Usually the other trainers speaks about the areas and lsa types and then shows what happens when you use them. Here you went from the design perspective of what we want to achieve and how to do that, which made the topic intuitive and easy to understand. You're a great teacher.
So many gold nuggets within this 30 minute video. Took me almost 4 hours to complete watching this video as I have to pause many times, think, and take down notes. Best "OSPF area types" video explanation so far.
There is not a better instructor on networking than this man right here. I've had the opportunity to learn from him in class. Unbelievable teacher, mentor, and a fantastic person!
No matter what Vendor equipment type you are responsible to managing, this is the best explanation for the various OSPF Areas types and in some regards OSPF LSA's as well. Thank you Narbik.
Thank you sir, thanks for the kind words. I have more for MPLS and L3/VPNs, if you are interested. learningnetwork.cisco.com/docs/DOC-33252 learningnetwork.cisco.com/docs/DOC-33253 learningnetwork.cisco.com/docs/DOC-33254
My deadly Notes: EVERY AREA NEEDS A DEFAULT ROUTE (as a pointer to a corresponding ABR either from External route or Internal) [Type1] - Each router generates a Type 1 LSA that lists its active interfaces, IP addresses, neighbors and the cost. LSA Type 1 is flooded only within an area. [Type2] - Type 2 LSA is sent out by the designated router (DR) and lists all the routers on the segment it is adjacent to. Type 2 LSA are flooded only within an area. It contains the information about DR's. [Type3]- Type 3 LSAs are generated by Area Border Routers (ABRs) to advertise networks from one area to the rest of the areas in Autonomous System. It contains the information about inter-area routes. [Type4] - It is generated by the ABR and contain routes to ASBRs. [Type5] - External LSAs are generated by ASBRs and contain routes to networks that are external to current AS. [Type7] - Stub areas do not allow Type 5 LSAs. A Not So Stubby Area (NSSA) allows advertisement of Type 5 LSA as Type 7 LSAs. Type LSA is generated by an ASBR inside a Not So Stubby Area (NSSA) to describe routes redistributed into the NSSA.
Sir you are explaining is ultimate and awesome. I never ever saw trainer like you. Request you to please share BGP & ASA Labs as well. Thanks for your time.
Amazing, the way you simplify OSPF area types, it was really awesome, this was a confusing topic for me ever, which has been cleared now, Thanks a lot Sir.
One of the best explanations of area's and LSA's I would have been very useful for me if I could take a screenshot of your board. The whole screen was never shown.
Was wondering why the instructor is using 100s of routes, thinking will confuse people. Damn i was wrong, it is awesome explanation. Wonder it might be hard if it was less routes. Thanks again.
Hi Narbik, thanks so much, what a great explanation. I hope that you might also share in details how those route are being flooded back and fourth in the domain.
Hello Sir, I have no words to say Thank you :) it was superb lecture with every minor detail capture for ospf area. Thank you Please share other lecture on OSPF bits as you mentioned you will be coming up ..Waiting for you video :)

This is by far the best video to learn about OSPF Area types.
the explanation of why we configure area stub command on each router is mindblowing. Had never read it anywhere before. Wow
