ASA supports route-based VPN with the use of Virtual Tunnel Interfaces (VTIs) in version 9.8 and later. we couldn't use the dynamic routing feature over policy base IPSEC.

I have installed a basic lab with Eve-ng. Not: Vti tunnel only support BGP protocol Also you can see the whole restriction for Asa
