Topology LB?

Topology load-balancing seems pretty straight-forward, however, since the GTMs can only make load-balancing decisions on LDNS servers, there will inevitably be users who are connected to a central DNS server outside their country who could be classified incorrectly. It doesn’t appear that the Topology table is available on the LTM’s.

Could an iRule on the LTM validate the source IP is still within the country IP ranges once the client actually connects to the LTM’s. If not, we could just redirect back or route to another pool?
