BIG-IP DNS Deployment

Hi there,

 

Looking for some guidance's. I have an LTM cluster with stretched VLAN's between two DC. Each DC has it's own Public address space. The same BIG-IP units are licensed with the DNS modules. The listener is the self IP of each of the BIG-IP units on the external vlan. When defining the server when deciding on the Product list, should this be BIG-IP System (Single) or Redundant System.

 

Appreciated any input based on implementations that you may have done.

 

Regards,
