Abstract

A method and apparatus for virtual private networks (VPNs) is described. A computer implemented method comprises determining a set of endpoints for a generic routing encapsulation (GRE) tunnel, determining a key (the key corresponding to a VPN), dynamically establishing the GRE tunnel with the set of endpoints and the key, and processing a set of GRE traffic for the VPN.
