System and method of dynamic establishment of virtual private networks using border gateway protocol ethernet virtual private networks technology

摘要

A method and apparatus of a network element that dynamically establishes a first virtual private network (VPN) tunnel is described. In an exemplary embodiment, the network element detects data destined for a first private subnet. In response to the detecting, the network element determines that a next hop for the data does not have an established VPN tunnel that allows access to the first private subnet. The network element further establishes the VPN tunnel and sends the data using the VPN tunnel.
