Good evening,

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

ospf link failure

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.


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?

Course material
It seems to me that we didn't talk in class about the part OSPF, LSA,... and the rest of the Link State module. We stopped at the slide 28.
So will these remaining slides of the Link State module be part of the exam?

And the same question for the end of the module on Bridges. Is the RSTP in the course material for the exam or not?
