Soft GRE

In soft GRE, only one side of the tunnel needs to be configured; the other end learns
the remote IP addresses of all remote tunnel endpoints by examining the incoming
GRE packets.
GRE tunnels can be automatically created when devices attach to the AP,
eliminating the need for each AP to be explicitly provisioned on the WLAN Gateway.
Because this soft GRE is stateless and the tunnel contexts are created based on
need, the WLAN Gateway does not need to maintain states for unused tunnels,
which improves scalability.
The operator can restrict the traffic going through the GRE tunnel based on the
SSIDs or LAN ports.
Figure 10 shows the soft GRE architecture.
