L2F

L2F stands for layer2 forwarding. L2F is used to create a secure tunnel across a public network. A virtual point to point connection is created between the user and the VPN gateway on the private network that the user is connecting to. L2F works at the link layer of the OSI model. L2F has no encryption. L2F is being replaced by L2TP. L2F is used for VPN.
