IPsec Tunnel: between BIG-IP LC to BIG-IP LC

Hi All,

My facing a challenge to create IPSec VPN tunnel between two BIG-IP LC devices.

Internal >> Firewall >> LC >> internet >> LC >> Internal.

BIG-IP LC >> BIG-IP LC, is their any config or Links docs for reference to deploy.

Any Configuration or Steps to initiate or any Videos which help us to deploy such scenarios.
