DMVPN (Dynamic Multipoint VPN): A Solution for Interconnection of Sites IPv6 over an IPv4 Transport Network [Full Text]

Abdou Karim FAROTA and Mor DIOUM

Abstract - The Dynamic Multipoint VPN (DMVPN) establishes at the request of the remote site VPN tunnels to remote sites. This allows the reproduction of a full mesh of VPNs which helps reduce latency when traffic goes up to a concentration site, saves bandwidth and greatly simplifies the deployment of VPN architectures. DMVPN service relies on the know-how of Cisco Routing and IPSec protocol allowing dynamic configuration of GRE tunnels, IPSec encryption and NHRP (Next Hop Resolution Protocol), OSPF and EIGRP protocols. This dynamic configuration of VPN tunnels associated with technologies such as quality of service (QoS) and multicast optimizes the application deployment sensitive to latency as the voice and video. DMVPN also reduces administrative tasks by eliminating the need to reconfigure a central VPN hub to add new peripheral routers or to establish connections between two of these peripheral routers.
