 App Pools will be on both DC associated to the VIP at each DC. We have single F5 at each DC, so I believe no broadcast GARPs on failover doesn't apply here I'm not mistaken.

OK - so it's not really an HA environment, it's just a standalone LTM in each DC.

 

Generally the recommendation is for having an HA pair in each DC, and using GTM/DNS to manage the DC to DC failover.

 

But as long as you can monitor the status of each DC to change the routes, it should work. But a conversation with your F5 Account Team probably would be useful.
