Mobile IP and the Tunnel Establishment Protocol (TEP) use GRE
for multiprotocol support. Mobile IP is a proposed standard, TEP is
a draft submitted to the MIP WG and it is a WG document.
So there is a couple of protocols (actually sharing most of the messages and
of
the code) which are going to use GRE as the mechanism you are talking about.
