Can F5 use virtual server of another F5 as pool member?

Hi

I have F5 in two separate zone (ie. zone internal,DMZ)

i want to use F5 internal zone LB to different virtual server in different F5 DMZ zone (pool member is VS_1 of F5_1 DMZ & VS_2 of F5_2 DMZ )

network Flow is

Client >> VS F5 internal LB >>>> LB between VS_1 of F5_1 DMZ & VS_2 of F5_2 DMZ >>> then each F5 DMZ will LB to their pool member respectively

F5 internal zone will LB virtual server of another F5

can this doable?

Is this will have issue? or prerequisite?
