This section allows you to set GRE configuration. The default mode is off.
Generic Routing Encapsulation (GRE) is one of the available tunneling mechanisms which
uses IP as the transport protocol and can be used for carrying many different passenger protocols.
The tunnels behave as virtual point-to-point links that have two endpoints identified by the tunnel
source and tunnel destination addresses at each endpoint.
The GRE Mode is on.
