You are a great lecturer! I am baffled over and over again during the course of these lectures on how smart the solutions to lets say the IPv4 Problem is.
No, I believe it has to keep its original source address. The source of that datagram was still B (where it was created), though it wasn't its directly connected partner
looks like a typo to me. But one discussion below added more understanding on the need to maintain source of datagram from B. This leads to another question - at E-F, why src still A, instead of D (where the IPv6 tunnel came from)?
Thanks to these videos, I have gone from 0 to familiar with the first half of your text's contents in 2 days! You are an incredible teacher.

Ey Jim, I just have a final exam literally of all your book, so this videos are just perfect! Please do more about the other chapters :)
Excellent lecture! Thanks so much for the great explanations, Sir.
excellent one, ty
ISPs just hate giving IPv6 addresses with prefix less than /64
I need /56 or /60 for my subrouters
One quick Question. How does the router know that the next hop router is of type IPv4, So i need to encapsulate it into an IPv4 datagram
Probably because its both IPv6/IPv4, and knows that its connected to the next IPv6 router via a IPv4 tunnel
its known because of the forwarding table. The forwarding table will tell you the next hop's IP and version type.
At 17:20, shouldnt it be B-to-C, C-to-D and D-to-E instead of B-to-C, B-to-C, B-to-C?
has to be a typo
No, I believe it has to keep its original source address. The source of that datagram was still B (where it was created), though it wasn't its directly connected partner
@@KBrown2480 you misunderstand. I am not referring to the src and dest fields in the red boxes. I am referring to the lines below the three red boxes.
Yeah it is . I think it’s a typo
looks like a typo to me. But one discussion below added more understanding on the need to maintain source of datagram from B. This leads to another question - at E-F, why src still A, instead of D (where the IPv6 tunnel came from)?
i love you
this is an excellent series of lectures, thank you!
the flow label is 20 bits long!!
