CCNP : understanding OSPF LSA types ( by sikandar CCIE(RS/SP) #35012 )

The link-state advertisement (LSA) is a basic communication means of the OSPF routing protocol for the Internet Protocol (IP). It communicates the router's local routing topology to all other local routers in the same OSPF area. OSPF is designed for scalability, so some LSAs are not flooded out on all interfaces, but only on those that belong to the appropriate area. In this way detailed information can be kept localized, while summary information is flooded to the rest of the network. The original IPv4-only OSPFv2 and the newer IPv6-compatible OSPFv3 have broadly similar LSA types.

Outstanding work sir. This is the best video on explaining the OSPF LSA types on the internet.

I was really scared of these LSA types. :-D I searched a lot on internet but none of them helped me to really understand what LSA's are. I found it very complicated. i just watched your video and guess what now i am thinking like how easy this concept was... :-D you explained everything in a very easy, simple way, without complicating things that even the dumb person like me can understand it. Thank you thank you so much from bottom of my heart. you saved my lot of time. god bless you buddy.

Hi Sikander-in LSA3 ABR will send updates between any 2area is it correct and not only area0 ? Is it ?

[riyassubair]

There is a mismatch in the video and its audio...
Did any one noticed that..

[hclconsult]

Good Job Sikander, Very well explained. One small correction, ASBR is Autonomous System Boundary Router not Autonomous System Border Router.
