DMVPN Insights

What is DMVPN?

DMVPN (Dynamic Multipoint VPN) is a Cisco software solution for building scalable VPNs. It uses mGRE (Multipoint GRE), NHRP (Next Hop Resolution Protocol), and optional routing protocols like EIGRP or OSPF to dynamically create VPN tunnels between branch offices and a central hub. This allows for direct communication between branches without having to route all traffic through the hub, improving latency and bandwidth utilization. DMVPN is commonly used to connect branch offices to a central headquarters, providing secure and reliable connectivity over the public internet.
