![]() ![]() ġ.In this post we will automate the deployment of a Cisco DMVPN network. Note: if you are interested in this article, and you can follow SPOTO where we will update more technical articles that will improve your ability to take the Cisco certification exams. Using DMVPN where possible is good for every company to help reduce WAN costs and increase bandwidth and reliability. They increase resiliency and redundancy.ĭMVPN deployment includes mechanisms such as GRE tunnel and IPsec encryption with next-hop parsing protocol (NHRP) routing, which aims to reduce the administrative burden and provide reliable dynamic connections between sites. DMVPNs eliminate additional network delays.Ĥ. Traffic between remote sites does not need to traverse the hub (headquarter VPN router).Ī DMVPN deployment eliminates additional bandwidth requirements at the hub.ġ. When data exchange between two branches is required (for example, for VoIP phones), the branch will contact the hub, get the necessary information about the other end, and create a dynamic IPsec VPN tunnel directly between them.ĭirect spoke-to-spoke deployments provide a number of advantages when compared to traditional VPN deployments: ![]() Each remote site has a router configured to connect to the VPN device (hub) at the corporate headquarters so that available resources can be accessed. The DMVPN service runs on VPN routers and firewall concentrators. ![]() This means that each site (branch) can connect directly to all other sites, wherever they are located. DMVPN essentially creates a mesh VPN topology. Traditionally, VPN connects each remote site to headquarters. ![]() Dynamic multipoint virtual private network (DMVPN) is a secure network, which can exchange data between sites without the need to transfer traffic through the (VPN) server or router of the organization’s headquarters virtual private network. ![]()
