DMVPN – Dynamic Multipoint Virtual Private Network 🔐🌐

DMVPN is a Cisco VPN technology designed to connect multiple branch sites securely using dynamic tunnels — without configuring point-to-point VPNs for every location.

Instead of managing hundreds of static tunnels, DMVPN builds them on demand.

How DMVPN actually works (no theory):

mGRE → Single tunnel interface, multiple dynamic peers

NHRP → Resolves private tunnel IPs to public WAN IPs

IPsec → Encrypts all traffic end-to-end

DMVPN Phases (know this for interviews):

Phase 1: Hub-and-Spoke (all traffic via hub)

Phase 2: Dynamic Spoke-to-Spoke tunnels

Phase 3: Optimized routing with NHRP redirect
