This session covers in detail the concepts of the Dynamic Multipoint VPN (DMVPN) solution. It starts with an overview of basic DMVPN functionality including in-depth descriptions of how Next Hop Resolution Protocol (NHRP) is used in DMVPN hub-and-spoke and dynamic spoke-spoke networks, including DMVPN Phase 2 and Phase 3 functionality and discussion and examples of using DMVPN for Network Virtualization with VRF-lite and 2547oDMVPN. The session also covers how DMVPN interacts with NAT, QoS, MPLS, and dynamic routing. This session is for designers, managers, and troubleshooters of extended corporate DMVPNs and for service providers that are deploying these services for their customers.
