DMVPN over two sub-interfaces

Unanswered Question

I need to configure a DMVPN spoke to join an existing DMVPN.

My problem is that the interface that connects to the Internet has a double feed. Basically fa0/0 is configured with two sub-interfaces fa0/0.X and fa0/0.Y.

My doubt is if I can put the tunnel source as fa0/0 simply and it will apply it on both? I know it is a fairly simple question but since I am about to apply it on a live system I really wanted to be sure.

Because ip addresses are assigned to sub-interfaces I think tunnel source should be pointing to sub-interfaces.
