That is a lot to visualize.  I do have one question.  What device is doing the DNS to access these LTM's.  Are you using BIG IP GTM/DNS or another platform like InfoBlox.  Side note on the APIC.  Those things are so over designed.  We got a Cisco CCIE in our department and he still has to contact Cisco TAC to get APIC to work as required for our needs.  Even with disabling the Virtual Server there is the Virtual Address List that has ARP enable by default.
