F5 Load Balancer Provider for Microsoft 2012 R2 SCVMM

Does a F5 Big IP Load Balancer Provider exist for Miscrosoft 2012 R2 SCVMM ?

 

How can I load balance traffic with an F5 Big IP LTM connected to the UNDERLAY (Physical) Network for VM's located inside the Cloud using the OVERLAY IP addressing space, without passing the traffic through the NVGRE Gateway ?

 

Can something like this be done ? The driver is to replace the Microsoft NLB with the F5 LTM HLB function.

 

thank you
