Description

Fortinet Auto Discovery VPN (ADVPN) allows to dynamically establish direct tunnels (called shortcuts) between the spokes of a traditional Hub and Spoke architecture.

After a shortcut tunnel is established between two spokes and routing has converged, spoke to spoke traffic no longer needs to flow through the Hub. Direct connectivity is provided.

Fortinet ADVPN was introduced in FortiOS 5.4.
