IPSec Virtual Tunnel Interface - VTI

IPSec Virtual Tunnel Interface (Cisco Systems)
IP security (IPsec) virtual tunnel interfaces (VTIs) provide a routable interface type for terminating IPsec tunnels and an easy way to define protection between sites to form an overlay network. IPsec VTIs simplify configuration of IPsec for protection of remote links, support multicast, and simplify network management and load balancing.

Virtual Tunnel Interface with IP Security - VTI

Configuring a Virtual Tunnel Interface with IP Security (Cisco Systems)
This document provides a sample configuration for a virtual tunnel interface (VTI) with IP Security (IPSec). This configuration uses RIP version 2 routing protocol to propagate routes across the VTI. With a VTI, VPN traffic is forwarded to the IPSec virtual tunnel for encryption and then sent out of the physical interface. This sample configuration also demonstrates the use of Cisco Quality of Service with VTIs.
