שאלה 3 במבחן זה סעיף b
רציתי לשאול בבקשה מדוע המסלול שייבחר ע"י
OSPF
הוא המסלול שמצויין בתשובות.
כתוב בשאלה כי משקל הקשתות הינו הזמן להעברת חבילה באורך מירבי.
ואם לא טעיתי בחישוב אז יוצא שהמסלול שנבחר לא ייתן את המסלול המהיר
ביותר

מה אני מפספס פה?

תודה רבה למי שעוזר

It confused as well:

According to their solution to 3.b it seems that the weights of the links is measured by propagation delay. Only this explains why the OSPF choses a different path.
However, then in 3.d they say that if D uses OSPF and the rest use RIP there is no change. This mixes everything:

If the above assumption (i.e. OSPF based on propagation delay) is correct there must be difference in 3.d (since D should chose to go to G via F).
Otherwise the OSPF should had chosen the same path as RIP, since transmission time completely dominates and force path with minimal number of routers..
