Starting to answer my own questions. I couldn't add multiple port VIPs to the pool, because if ANY of those ports were available it would keep the entire VIP (Which is all GTM/DNS cares about) active. So if ANY port fails I have to fail the entire VIP.

 

Seems like the best method is back to just having two 'primary' VIPs in the pool, one at each Datacenter, and adding all the other related ports as dependencies to those. That way if any of the ports fail, they would fail the primary VIP and take it out of the GTM pool.

 

Another option instead of dependency, maybe setup a monitor for EACH port on the pool, that way if one of the VIPs failed any one of the monitors it would take it out of the pool?

 

Anything else I am missing?
