GTM and LTM sync links

We have DC1 and DC2 DC1 have one GTM1 and LTM1 (HA pair LTM1-A and LTM1-B) DC2 have one GTM2 and LTM2 (HA pair LTM2-A and LTM2-B)

 

When I am going to add LTM1 to GTM1 what ip I has to use self ips (LTM1-A and LTM1-B) or floating ip LTM1? What ip I can use for create sync between GTM1 and GTM2 self or floating?

    When you add an LTM to the GTM config you specify the IP address of the LTM itself (i.e. non-floating).

     

    The GTM needs to use the non-floating self-ip so that it knows exactly which device it's communicating with, plus it wants to gather information (Via the 3dns daemon) continually whether the device has active traffc-groups on it or not.
