There is a small error at 4:20 when I show the SPTs.... R4's SPT should show a cost of 20 for the serial link (not 10), and the network attached to R4 at the top of the tree should be 3.3.3.0 not 4.4.4.0. The concept I am explaining is still the same, just those small typos. Sorry for that. I have fixed the image in my OSPF document for future use/distribution.
