Protocol 47 is the Generic Routing Encapsulation protocol or GRE for
short. It is used primarily to tunnel traffic from non-adjacent routers
without being affected by the transit routers. It is often used to
pass routing information and to allow communications between 2
non-routable networks.
To my
knowledge GRE offers virtually no encryption of the data. For that you
need IPSEC or some other security mechanism.
