Abstract
Systems, methods, and other embodiments associated with any-to-any multicasting in a tunnel based virtual private network (VPN) are described. One example method includes calculating a resolved address for an unknown reverse path forwarding (RPF) neighbor in an any-to-any multicasting route. The resolved address is calculated using next hop resolution protocol (NHRP) resolution. The address is to be resolved based on control plane traffic. The NHRP address resolution is not to affect unicast routing. The example method may also include establishing the any-to-any multicasting route. Since the multicasting route is any-to-any (e.g., spoke-to-spoke), the multicasting route is not required to include a hub in the logical hub-and-spoke network.
