Solution for duplicate F5 Self IP's at two datacenters using OTV

so your looking to run each F5 as Active/Active in D/C A / B? and you want each unit to have the same exact self IP's and entire configuration?

You potentially configure a new Route domain and use the same configuration on your B side F5 along with new physical links to you D/C Core to allow the use of the same configuration..

If you block each F5 from talking and they were previously setup as Active/Standby i guess you could achieve this as well however the B D/C F5 will have the secondary self-ip and no the primary self-IP although it will share the same floating IP.
