A DMVPN allows organizations to build a VPN network with multiple sites, without the need to configure devices statically. A DMVPN creates a mesh VPN topology. In this "hub and spoke" mesh, each remote sites router is configured to connect to the companys VPN hub device to provide access to the required resources.
Benefits. DMVPN provides the capability for creating a dynamic-mesh VPN network without having to pre-configure (static) all possible tunnel end-point peers, including IPsec (Internet Protocol Security) and ISAKMP (Internet Security Association and Key Management Protocol) peers.
Dynamic Multipoint Virtual Private Network DMVPN is a solution which enables the data to transfer from one site to another, without having the verification process of traffic. That use to be held at main VPN server of the concerned organization.
DMVPN Dynamic Multipoint VPN is a routing technique we can use to build a VPN network with multiple sites without having to statically configure all devices. Its a “hub and spoke” network where the spokes will be able to communicate with each other directly without having to go through the hub.
Dynamic multipoint virtual private network DMVPN allows IPsec VPN networks to better scale hubtospoke and spoketospoke designs, thereby optimizing performance and reducing latency for communications between sites.
