01
Deploy a hub router at HQ with firewall and NHRP server to terminate mGRE/IPsec tunnels from all spokes.
02
Use DMVPN dynamic hub-and-spoke tunnels from each branch router to the hub, with NHRP enabling direct spoke-to-spoke connectivity as needed.
03
Keep branch LAN segments simple with access switches, PCs, APs, and IP phones behind each spoke router.
Reusable for any multi-site enterprise network that needs VPN-based WAN connectivity with dynamic spoke-to-spoke routing and a hub-and-spoke overlay.
