(1)Layer 2 Tunneling Protocol (L2TP) is a subset of PPP(Point-to-point) protocol. (2)The basic use of it is enabling layer 2 communication over IP(Layer 3) (3)The advantage is that, in general routing enviroment, all the communication is done on layer 3.If you want transparent network between your tunnels.You have to implement L2 communication Overview - TechLibrary - Juniper Networks Types of VPNs, VPNs and Logical Systems, Understanding Layer 3 VPNs, Supported Layer 3 VPN Standards, Understanding Layer 3 VPN Forwarding Through the Core, Understanding Layer 3 VPN Attributes, Routers in a VPN, Introduction to Configuring Layer 3 VPNs SolutionBase: Introduction to SSL VPNs - TechRepublic May 05, 2005 Is VPN a layer 3 concept? - Network Engineering Stack Exchange
