Jan 23, 2017 Is VPN a layer 3 concept? - Network Engineering Stack Exchange There are layer-2 and layer-3 VPNs. "VPN" is a term used for a tunnel combined with encryption. A tunneling interface encapsulates an inner packet (or frame) in an outer packet. This inner packet is then transported to the far tunnel end, according to the outer packet, and decapsulated again. For the inner packet the tunnel looks like a direct Understanding MPLS Layer 3 VPNs - TechLibrary - Juniper
Layer 2 tunneling is predominantly used in a Remote Access VPN to create point-to-point tunnels between a remote client and a VPN server. Layer 3 tunneling uses network layer tunneling protocols, such as IPSec in the tunnel mode and IP over IP, for the exchange of data packets. These protocols use packets as a medium of exchange.
Carrier Ethernet Services and Layer 3 VPNs. Many core networks are built over IP/MPLS both nationally and internationally. IP/MPLS or L3VPN is a technology where the traffic is carried over pseudowires (PW) over MPLS Label Switch Paths (LSPs) tunnels. The forwarding is L3-based. The infrastructure comprises routers that are MPLS-capable.
