Maria, Couple of clarifications.

[Lucy] In case A, you forward on IP address. In case B, do you also always forward on IP address? How do you set up a policy per a subnet? > It is just that the virtual subnet has no locality across a data-center. [Lucy] Do you mean that both case A and B only apply within a DC?
