PPTP (Point-to-Point Tunneling Protocol) operates at Layer 2 of the OSI model, which is the Data Link layer. This layer is responsible for establishing direct connections between two nodes on a network and enabling the encapsulation of packets into frames for transmission. PPTP encapsulates PPP frames into IP datagrams for transmission over an IP network.
