V3PN Solution Reference Network Design


Core Issue

The IPSec Voice and Video Enabled VPN (V3PN) Solution Reference Network Design (SRND) extends the Architecture for Voice, Video and Integrated Data (AVVID) by enabling voice and video applications to be transported over a site-to-site IPSec VPN. Just as Enterprise implementers expect to run these applications over a private WAN (like Frame Relay or ATM), they also expect to run voice and video across their VPN implementation with the same quality and level of service. Furthermore, the Enterprise implementer should be able to do so and have the VPN be fairly transparent to these applications.


To provide these capabilities, Cisco designed the IPSec V3PN, which integrates three core Cisco technologies:

  • IP Telephony
  • QoS
  • IPSec VPN

The result is an end-to-end VPN service that can guarantee the timely delivery of latency-sensitive applications like voice and video.

For more information, refer to Voice and Video Enabled IPSec VPN (V3PN) Solution Reference Network Design (2MB PDF file).

To see which versions of Cisco IOS  Software support VPN, refer to the Find software with the features I need section of Software Advisor.
