Hi can anyone help me in detail about ACI vs NSX, why would you pick one over another ? 

If Cisco Fabric Underlay and control plane is on Different IP ranges, can the data Run on totally diff IP ranges for tenants and most of them can have overlapping IP space ?  

Hi Team,  Why cisco suggested only OSPF for remote leaf extension, Shouldn't the whole idea be to have IP backbone reachable fo extension.  We dont run OSPF on any switches , what other options are vailable BGP or EIGRP or  Static DR ? REgardsSaurabh...
