Multiple Sites - Multiple F5's - Multiple Exchange Servers

Currently we are in the proof of concept stage with prod deployment coming soon. We have it configured with each site having its own DNS name. We have 1 F5 in SiteA which DNS for CAS-Array A points to and then one for SiteB as well. We have created 2 DNS records for outlook.x.x each of which points to one of the F5's (for round robin). This is what we use initially to configure client outlook profiles and (i presume) they are being directed to the appropriate cas-array/f5 from.

 

 

So you are saying that having both CAS-Arrays resolved to the same IP wont cause any issues or loops for exchange?
