Explanation
DMVPN (Dynamic Multipoint VPN) uniquely supports both hub-and-spoke and spoke-to-spoke connectivity in a single, scalable architecture. In Phase 1, all traffic flows through the hub. In Phase 2 and Phase 3, spoke sites can dynamically build direct tunnels to each other on demand using NHRP (Next Hop Resolution Protocol), enabling spoke-to-spoke communication without permanently configured tunnels. Standard IPSec VPN is typically point-to-point or static hub-and-spoke and does not natively support dynamic spoke-to-spoke tunneling.
