VPN clarification question

Hi Experts,

Just a quick clarification question about VPNs:

Question: According to the below points, does Peer to peer VPN model only
include L3VPNS? Or I don't have to relate them?

As for Overlay VPNS it can include Layer2 or layer3(GRE.).

L2 VPNS:

p-2-p: AToM (Ethernet - Frame Relay - ATM) - L2TPv3 (used in pure IP based
core solution)

multipoint: VPLS

L3VPNS:

GRE/IPSEC - MPLS BGP

Thanks,

Hussam
