See Layer 2 Tunnelling Protocol.
Layer 2 Tunneling Protocol. Developed jointly by Cisco Systems, Inc. and Microsoft Corp., L2TP performs end-to-end encapsulation between client and server.
Layer 2 Tunneling Protocol. A standard Layer 2 tunneling protocol that was developed from earlier protocols, i.e. L2F and PPTP. L2TP is used in VPN. Also see tunnel and VPN.
An acronym for Layer 2 Tunnelling Protocol
Layer 2 Tunnelling Protocol. A hybrid protocol created by combining PPTP and Cisco's Layer 2 Forwarding, to provide encapsulation of non-TCP/IP LAN protocols more efficiently than either protocol did on its own.
Layer 2 Transport Protocol is based on IPSec and combines Microsoft® PPTP and Cisco Systems® L2F tunnelling protocols.
Layer 2 Tunneling Protocol, an emerging standard for "tunneling" a variety of protocols across an IP connection. It is being forged as a compromise between Cisco's Layer 2 Forwarding (L2F) and Microsoft's (et al) PPTP.
Layer 2 Tunnel Protocol. 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 Tunneling Protocol. A protocol from the IETF for creating VPNs over the Internet. It supports non-IP protocols such as AppleTalk and IPX as well as the IPSec security protocol.
A tunneling protocol designed to encapsulate data link frames e.g. PPP frames inside IP packets. Does not provide encryption for encapsulated frames.
A protocol that combines the features of Microsoft's Point-to-Point Tunneling Protocol (PPTP) and Cisco Systems' Layer 2 Forwarding (L2F) to support multiprotocol or private-address Internet Protocol (IP) traffic across a public IP network. L2TP is a mature Internet Engineering Task Force standard that has been widely implemented. (See L2F and PPTP.)
Layer 2 Tunneling Protocol. Provides a means for tunneling IP traffic in layer 2. Can be used with IPsec to provide authentication. RFC 2661
Layer 2 Tunneling Protocol. L2TP is an extension to the Point-to-Point Protocol (PPP), which is utilized with Virtual Private Networks (VPNs). L2TP supports multiple protocols and unregistered and privately administered IP addresses over the Internet. This allows enterprise customers to outsource dialout support, thus reducing overhead for hardware maintenance costs and 800 number fees, and allows them to concentrate corporate gateway resources.
(Layer 2 Tunneling Protocol) A merging of features from PPTP and Cisco's L2F. It is used to encapsulate PPP frames and transmit them across a TCP/IP network. As an IETF standard, L2TP is supported by many VPN providers.
Layer 2 Tunneling Protocol. An IETF standard that combines aspects of Cisco Layer 2 Forwarding Protocol (L2F) and Microsoft's Point-to-Point Tunneling Protocol (PPTP) for implementing VPNs.
(Layer 2 Tunneling Protocol) is a secure protocol used for connecting VPNs (Virtual Private Networks) over public lines such as the Internet. It is essentially a combination of two other secure communications protocols: PPTP and Cisco Systems' L2F.
Layer 2 Tunneling Protocol. An IETF standard tunneling protocol for VPNs. See also IETF and VPN.
(Layer 2 Tunneling Protocol) -- An IEEE standard for tunneling that includes the ability to terminate tunnels at either the NSP or enterprise network, to apply access policies at the firewall, and to perform tunnel switching.
Layer 2 Tunnel Protocol. A tunneling protocol that permits separating the remote access network function - terminating the PSTN circuit, for example - from the local network access operations such as authenticating and authorizing the remote user.
Layer 2 Tunneling Protocol. An Internet Engineering Task Force (IETF) standards track protocol defined in RFC 2661 that provides tunneling of PPP. Based upon the best features of L2F and PPTP, L2TP provides an industry-wide interoperable method of implementing VPDN.
(Layer 2 Tunneling Protocol) - An IETF protocol used for virtual private networking.
Layer Two Tunneling Protocol.
Layer 2 Tunneling Protocol. A standards-based protocol providing remote users with dial-in access to a corporate network, via an existing ISP network. See also Extranet, VLAN.
Layer 2 Tunneling Protocol. A procedure for secure communication of data across a Layer 2 network that enables users to establish PPP sessions between tunnel endpoints. L2TP uses profiles for individual user and group access to ensure secure communication that is as transparent as possible to both end users and applications. See also tunneling protocol.
An industry-standard Internet tunneling protocol. Unlike Point-to-Point Tunneling Protocol (PPTP), L2TP does not require IP connectivity between the client workstation and the server. L2TP requires only that the tunnel medium provide packet-oriented point-to-point connectivity. The protocol can be used over media such as ATM, Frame Relay, and X.25. L2TP provides the same functionality as PPTP. Based on Layer 2 Forwarding (L2F) and PPTP specifications, L2TP allows clients to set up tunnels across intervening networks. See also: Asynchronous Transfer Mode (ATM); Internet Protocol (IP); Point-to-Point Tunneling Protocol (PPTP); tunnel
A Layer 2 protocol that can work in a non-IP enterprise environment. L2TP is used primarily by service providers to encapsulate and carry VPN traffic through their backbones.
