DMVPN spokes can use DHCP or static addressing for the transport and overlay networks. DMVPN was released in three phases and each phase was built on the previous one with additional function skies.All three phases of DMVPN need only one tunnel interface on a router, and the DMVPN network size should accommodate all the endpoints associated with that tunnel network. DMVPN uses generic routing and encapsulation techniques like GRE for tunnelling next hop resolution protocol, NhRP for OnDemandforwarding and mapping information, and IPsec to provide a secure overlay network to address the deficiencies of site-to-site VPN tunnels while providing full mesh connectivity. DMVPN is a Cisco solution that provides a scalable VPN architecture. In this section we will talk about theDMVPN Fundament's dynamic multipoint virtual private network.
