CCIE Security - VPN DMVPN Dual Hub

DMVPN (Dynamic Multipoint VPN) Dual Hub is a scalable and resilient VPN architecture that enhances redundancy and load balancing in enterprise networks. By leveraging two hub routers, this design ensures seamless failover and optimized traffic distribution, improving network reliability.

DMVPN uses mGRE (Multipoint GRE) tunnels and NHRP (Next Hop Resolution Protocol) to dynamically establish direct spoke-to-spoke communication while maintaining centralized control.

Integrated with IPsec encryption, DMVPN Dual Hub provides a secure, flexible, and cost-effective solution for large-scale WAN deployments, ensuring uninterrupted connectivity even in case of hub failures.
