Networking Basics - OSPF Theory

[@nishan_nb]

The power of explaining it in such a way, that it is more easy to comprehend, is a gift. I am very thankful for that.

[@dhruvkhurana7452]

This is by far the best explanation of OSPF on the whole Internet!! Thank you Kevin

[@terrymaina6146]

Oh my God!!this explanation made my life so easy...you are God sent Sir.

[@bobbyb42]

I've looked all around youtube for networking videos, and most of them aren't for me. Your videos are organized well, have a good pace, and help me visualize things well, among other things. Thanks for making these!

[@androidery1999]

Agree. So glad I discovered his videos. Very easy to follow and I love the metaphors.

[@jimboelterdotcomm9153]

Love the "puzzle piece" metaphor - really helps to comprehend the process.

[@TheCartographeraoe]

Phenomenal explanation of the overall theory. Really put the details in perspective for me. Thanks Kevin!

Its unlikely, that navigation uses Dijkstra. It most likely uses A* because it has geolocation reference and can infer proper metric to the destination.

[@Tushartech91]

Hello sir, can anyone explain me why area 0 is called backbone area, why only 0 is used? why so specific?

[@NUVOILLUSR5671]

Backbone because it is the one area that all ABRs must have an interface connected to if you are dealing with multiple areas. I’m not sure why it is restricted to 0, but I assume for consistency in the same sense that on switches the default native VLAN is always VLAN 1.
