I can answer part of your question:

 

> so my question is can we create a VIP using a separate IP pool other than F5 interface IP network?

 

You can, and they will be advertised using a routing protocol (if the Virtual IP is configured with Route Advertisement). Note that these VIPs do not broadcast GARPs on failover, because they do not share address space with a self-IP on a vlan.

 

But as for your design, I'm not sure I quite understand it.

Where is the pool going to be for the VIP (DC1 or DC2 or both)?
