It differs from traditional VPNs in its ability to establish dynamic communication tunnels without requiring manual configuration for each site. Connections are initially established using a hub-and-spoke architecture, then direct communications between spokes are possible once the tunnels are established. This project aims to test and demonstrate the effectiveness of the DMVPN technology. By simulating the different phases, it evaluates the ease of establishing tunnels between remote sites and the central hub, as well as the ability of remote sites to communicate directly with each other. This makes it possible to check the performance of the network in the face of different usage and maintenance scenariosfrDMVPNNHRPSpokeVPNRoutingThesis
