Hello Diptish,
Although I haven't worked on this lab yet, I'm on lab 3 so getting
there. I did take a look at it. And basically you only need 1 virtual
link from R2 to R3, because ABR router R1 is connected to Area 11 and
Area 0, ABR router R5 is connected to Area 0 and Area 22. ABR router R3
is connected to Area 33, Area 22, and Area 1. So you only need 1 virtual
link from R2 to R3. The question did not mention anything if the links
from R2 to R3 were to fail. So that is why they don't have another
virtual link from R3 to R5. Im not sure I see why you would want
another virtual link from R3 to R1. So the book did not ask to provide
redundancy, so that is why there is only one virtual link.

Subject: CCIE R & S practice labs : LAB 4 ...
hi everyone ,
In the R&S practice lab book , lab 4 . I think
apart from the one Virtual link between R3 and R2
there should be 2 other virtual links from R3 to R5
and R3 to R1 .
To explain , in case the framerelay between r3 and
r2 fails the area 33 will get isolated .. but if we
have R3-R5 Virtual link than there wont be any
problem.
And if Framerelay between R2 and R3 fails and also
if Framerelay connection of R5 fails still we have
connection through R3-R1 virtual link which wont
isolate area 33.
Am i thinking in right directions ??? do let me
know .
Regards ,
diptish.
