LSVPN (Large Scale VPN)
Resolution
The Large Scale VPN feature simplifies the deployment of the traditional hub and spoke VPNs. This solution provides administrators with the ability to quickly deploy enterprise networks with several branch offices or telecommuters to securely access resources at a central site, with a minimum amount of configuration required on the remote devices. It uses certificates for device authentication, and IPSec to secure data.
