Hi Hassan,

As I know, a VPN connection can not act like/be/backup a trunk link. You can open up a question as "Backup trunk link over S2S VPN" in "Network Infrastructure" in "WAN Routing & Switching" section to make sure.

A workaround would be configuring Dynamic routing protocols with high costs, but that would not work if you have same VLANs at both sites.
