Section 12.10.1
Understanding DMVPN
Dynamic Multipoint Virtual Private Network (DMVPN) is a routing solution for building scalable and secure VPN
networks. It allows network designers to rapidly deploy routers for medium to large enterprises without having to
configure static connections between all devices.
DMPVN can be deployed in one of two ways.
• Hub-and-Spoke
• Spoke-to-Spoke
RUGGEDCOM ROX II supports hub-and-spoke deployments where a central router (the hub) uses Multipoint
Generic Routing Encapsulation (mGRE) to establish GRE tunnels with one or more routers (the spokes). When
spokes need to send traffic to one another, they send it to the hub first and the hub directs the data packets to the
appropriate destination. This method allows network designers to avoid the complex task of defining static GRE
tunnels for each possible connection.
