Abstract:
A method of establishing an L2TP tunnel between a first IP network and a first private IP network comprising the steps of:coupling a routing device of the first IP network to a public network; coupling a routing device of the first private IP network to the public network; initiating an L2TP tunnel from either the routing device of the first IP network or the routing device of the private IP network; authenticating the first IP network; providing the first IP network with an IP address from an address space of the first private IP network; maintaining the L2TP tunnel between the routing device of the first IP network and the routing device of the second private IP network; tunneling data traffic between the first and the second IP network over the public network via the L2TP tunnel; and utilizing a control mechanism for providing L2TP tunnel traffic error correction.
