Referred to this group by a Cisco friend...  I apologize in advance if this
message does not fall within the parameters of the group, but after reading
the guidelines, I think it does.

I'm doing quite a bit of research on VPN architecture, and can not confirm
from the information I have found, that the GRE protocol operates at layer 2
and is specifically for tunneling, and does not do encryption.  Can someone
confirm this?

Thanks for your time!
