Explanation

A virtual tunnel interface (VTI) is used to configure an encrypted, route-based site-to-site VPN on Cisco routers, allowing secure connections between the router and cloud environments. VTIs provide a virtual interface for IPsec, making it easier to manage and route traffic over encrypted tunnels without needing to configure complex access control lists (ACLs) for each connection. This method is widely used for VPN connections to cloud environments, where route-based VPNs are commonly supported.
