The entire IT industry is already acquainted with VPN and its functions which provide immense help to us in using internet in private and a more secure way. Along with that there is also one new specific point to understand i.e. dynamic multipoint VPN. It is referred to another safe way consisting of secure network where internet can pass easily and exchange data between sites. There is no need to pass any traffic through an organization’s headquarter i.e. virtual private network server or router. VPN and DMVPN work in a complete different way and have different features which help people differently. What exactly VPN does? It traditionally connects every remote site to the headquarters but DMVPN is its very opposite which essentially creates a mesh VPN topology. There is a straight permission of connecting each site directly with all other sites without thinking of where they are located. This is the main specialty DMVPN holds with it and these are more preferable which eliminates additional network delays.
This DMVPN service runs accordingly on VPN routers and firewall concentrators. Every remote site contains a router as we know thus those router needs to be configured to connect to the company’s headquarters VPN device or hub. This connection from router to VPN device provides access to the resources available. If in case the two sites are needed to exchange data between each other for a VoIP telephone call – which probably means the site will contact the device first and then obtain the necessary information needed about the other end and this information will create a dynamic IPSec VPN tunnel directly between them.
Therefore, DMVPN is that function which allows direct spoke to spoke deployments which provides a number of advantages than compared to traditional VPN deployments. The actual benefit we get from it is, it conserve WAN bandwidth, and lower the costs for VPN circuits.
