Good evening,

slide 60:
Why do we have [40,2] for the path 30->50->40?
Shouldn't we have [30,2]?

Thanks.

Hi,

In the lecture for link state routing, why can't we pass to X5 a packet to A1? We could imagine X5 forwarding it to X3 and X3 forwarding it to A1. I know it is not optimal, but it seems to work.

Thanks,

Good luck for tomorrow.

Exo 4.3 Q2
I have a problem with question 4.3.2. The question is: is there a case where the first option bit should be considerded as an error? The answer says that in some cases, you need to set the option bit to 1. I don't understand the connection. Could you develop the answer please?
