Thirded. There are any number of VPNs where the VPN is set up by some form
of mutual agreement - no negotiation, no connection, merely one end sending
packets in an agreed format and simultaneously agreeing to process incoming
The categorisations I would choose are:
1. VPN by mutual agreement (and where the connection cannot, typically, be
rejected) - this would include MPLS, GRE, l2tpv3 and VLANs
2. VPN where we provide one set of credentials to the far end, the VPN must
be activated and may drop and be reactivated, and the connection is
authorised or rejected on those credentials
3. VPN where we're an endpoint with (possibly) many sets of credentials and
we authorise incoming connections.
(2) and (3) would presumably be the same set of protocols and include
openvpn, ipsec and friends.
I'm not sure that that covers all the cases, so please chime in with your
