Concentrator
In a hub-and-spoke configuration, connections to a number of remote peers radiate
from a single, central FortiGate unit. Site-to-site connections between the remote
peers do not exist; however, VPN tunnels between any two of the remote peers can
be established through the FortiGate unit “hub”.
In a hub-and-spoke network, all VPN tunnels terminate at the hub. The peers that
connect to the hub are known as “spokes”. The hub functions as a concentrator on the
network, managing all VPN connections between the spokes. VPN traffic passes from
one tunnel to the other through the hub.
You define a concentrator to include spokes in the hub-and-spoke configuration.
