Abstract
A method, apparatus and computer program product for providing secure multipoint Internet Protocol Virtual Private Networks (IPVPNs) is presented. A packet lookup is performed in order to determine a next hop. A VPN label is pushed on the packet, as is an IP tunnel header. Group encryption through the use of DGVPN is further utilized. In such a manner secure connectivity and network partitioning are provided in a single solution.
