(Level 2 Forwarding) L2F permits tunneling of link-layer frames. L2F passes protocol-level packets through the virtual tunnel between endpoints of a point-to-point connection.
Layer 2 Forwarding. Protocol that supports the creation of secure virtual private dial-up networks over the Internet.
Layer 2 Forwarding. A Layer 2 tunneling protocol developed by Cisco. Also see tunnel and VPN.
Layer 2 Forwarding. A Layer 2 tunneling protocol that enables an ISP or other access service to create a virtual tunnel to link customer remote sites or remote users with corporate home networks. In particular, a network access server (NAS) at the ISP point of presence (POP) exchanges PPP messages with the remote users and communicates by L2F or L2TP requests and responses with the customer tunnel server to set up tunnels.
Layer 2 Forwarding. A protocol from Cisco for creating virtual private dial-up networks over the Internet. It has been combined with PPTP in the L2TP protocol.
A tunneling protocol developed by Cisco Systems. L2F encapsulates Point-to-Point Protocol (PPP) packets within Internet Protocol (IP) packets. This provides the significant benefit of being able to use private IP addresses across a virtual private network (VPN) by hiding them (via encapsulation) from the public network. This concept is important because many enterprises make use of private addressing schemes that conflict with public Internet addressing. See tunneling, PPP and VPN.
Layer 2 Forwarding. A tunneling protocol enabling remote access to corporate networks across the public Internet. See also Extranet, VPN.
