One of our customers had to provide end-to-end IP transport across their enterprise network for an outsourced video surveillance solution. We implemented a true VPN solution for them (the hosts in the enterprise network cannot access the surveillance equipment and vice versa) using the Multi-VRF feature available in all recent Cisco IOS releases. The solution is described in the March IP Corner article “Add a VPN to an Enterprise Network with Multi-VRF Functionality”.
