IPSEC tunnel St0 creation on SRX

Hi everybody,

Let say we want to establish Route based IPSEC tunnel (site to site) between two SRX, we configured our IKE phase1, Phase2 policies, and bind it to tunnel st0.1 using:

Set security ipsec vpn IPSEC-VPN bind-interface st0.1

My question is how do we create this tunnel interface? Is it created because of the above command?

Thanks,
