VIRTUAL TUNNEL INTERFACES
Cisco® IPSec VTIs are a new tool that customers can use to configure IPSec-based VPNs between site-to-site devices. IPSec VTI tunnels provide a designated pathway across a shared WAN and encapsulate traffic with new packet headers, which helps to ensure delivery to specific destinations. The network is private because traffic can enter a tunnel only at an endpoint. In addition, IPSec provides true confidentiality (as does encryption) and can carry encrypted traffic.With IPSec VTIs, users can provide highly secure connectivity for site-to-site VPNs and can be combined with Cisco AVVID (Architecture for Voice, Video and Integrated Data) to deliver converged voice, video, and data over IP networks.
BENEFITS:
• Simplifies management---Customers can use the Cisco IOS® Software virtual tunnel constructs to configure an IPSec virtual tunnel interface, thus simplifying VPN configuration complexity, which translates into reduced costs because the need for local IT support is minimized. In addition, existing management applications that can monitor interfaces can be used for monitoring purposes.
• Supports multicast encryption---Customers can use the Cisco IOS Software IPSec VTIs to transfer the multicast traffic, control traffic, or data traffic---for example, many voice and video applications---from one site to another securely.
• Provides a routable interface---Cisco IOS Software IPSec VTIs can support all types of IP routing protocols. Customers can use these VTI capabilities to connect larger office environments---for example, a branch office, complete with a private branch exchange (PBX) extension.
• Improves scaling---IPSec VTIs need fewer established security associations to cover different types of traffic, both unicast and multicast, thus enabling improved scaling.
• Offers flexibility in defining features---An IPSec VTI is an encapsulation within its own interface. This offers flexibility of defining features to run on either the physical or the IPSec interface.
