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.

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

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.

Without a doubt the best ospf types explanation on the web. Brilliant!

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!

Best video on ospf area...thanks a lot....

Great explanation on this topic. Thank you for your help!

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.
