Abstract

This document specifies a protocol which allows various Layer 2 and Layer 3 protocols to be tunneled through an IP network. VTP does not specify any change to the protocol to be tunneled. It describes the mechanisms for dynamically establishing and maintaining secure IP tunnels, and carrying multiprotocol data over those tunnels. VTP can be used in the implementation of Virtual Private Networks (VPNs). A client-server architecture is defined in order to decouple functions which exist in the tunnel initiation node and those in the tunnel termination node. This protocol can be implemented in network devices such as network access servers, routers and application servers. VTP specifies a Mobile IP-like message exchange protocol to create and manage IP tunnel sessions dynamically. VTP uses the GRE (Generic Routing Encapsulation) mechanism to encapsulate multi-protocol payload traffic.
