bigip_add with GTM HA Pairs

I have two datacenters, in each datacenter, i have two GTM's that are running in HA pairs.

 

 

DC A

 

A-GTM-01 (Active)

 

A-GTM-02 (Standby)

 

Floating IP

 

 

DC B

 

B-GTM-01 (Active)

 

B-GTM-02 (Standby)

 

Floating IP

 

 

When i configure synchronization, how should i run bigip_add? When i run it on A-GTM-02, should i include all the self-ip's of the three other boxes, whether they are standby or not? Or on B-GTM-01/02, do i just run bigip_add the floating ip of the HA pair in DC A.

 

 

Thanks!
