What is Cisco DMVPN?

Cisco DMVPN (Dynamic Multipoint VPN) is a Cisco IOS Software feature that provides a method to build scalable IPsec VPNs. It dynamically creates VPN tunnels between spoke routers as needed, allowing direct communication without needing to route traffic through a central hub for every communication. It's commonly used for building large-scale VPN networks, such as those connecting branch offices to a central headquarters, enabling secure and efficient communication and data transfer.
