You only need one PVC per remote in a hub & spoke environment, which in your
example would be a total of two PVCs for the whole network. Even if you were
to design a full mesh it would only take 3 PVCs to connect each site to the
other two. R1-R2-R3-R1 (I suck at ASCII art).
Think about it, if you have two PVCs on the same physical interface, going
to the same location, what have you accomplished except to include more
overhead? The second PVC can't be used for redundancy or load balancing if
it's on the same physical circuit.
Does that help?

If you had 3 locations in a hub and spoke topology,
then you would want two pvcs going to each
site...(using subinterfaces), how do the numbers
change as you add remote sites...
e.g. if you add the 4th site, do you have to add a pvc
to every other site?, totalling 3 pvcs/subinterfaces ?
so would that mean if you had 100 sites it would
require n-1 (99) pvcs/dlcis/subints per location...?
i may be way off
-thanks
