Which type of VPN routes packets through virtual tunnel interfaces for encryption and forwarding?
- IPsec virtual tunnel interface
- GRE over IPsec
- dynamic multipoint VPN
- MPLS VPN
| Explanation & Hint:
The type of VPN that routes packets through virtual tunnel interfaces for encryption and forwarding is an IPsec virtual tunnel interface (VTI). IPsec VTI creates a secure tunnel for transporting IP traffic using IPsec encryption. Unlike traditional IPsec VPN configurations which rely on crypto maps, VTI provides a routable interface that can be used similarly to any other physical interface, allowing for the use of routing protocols and simplifying the configuration process for IPsec VPN. |
