This deployment model is DMVPN in its simplest form. Single DMVPN Network/Cloud - Single Tier Headend Architecture It’s time now to take a look at each deployment model. Tunnel Protection – IPSec Encryption that protects the GRE tunnel and data.Dynamic Routing (Next Hop Resolution Protocol).In every case a complete DMVPN deployment consists of the following services, also known as control planes: Dual DMVPN Network/Cloud – Dual Tier Headend Architecture.

Providing configuration for each deployment model is out of this article’s scope, however, we will identify key services used in each deployment model along with their strong and weak points.įuture articles will cover configuration of all DMVPN deployment models presented here.įollowing are the most popular DMVPN deployment models found in over 85% of DMVPN networks across the globe: At the end, it’s all a matter of experience. Speaking of implementation, no matter how complex the DMVPN network might get, it’s pretty straightforward once it's broken down into sections.Įngineers already working with complex DMVPNs can appreciate this and see the simplicity in configuration they offer. The fact that there is a variety of DMVPN models, each one with its caveats and requirements, means that almost any VPN requirement can be met as long as we have the correct hardware, software license and knowledge to implement it. There is a number of different ways an engineer can implement a DMVPN network. Those seeking help to configure a DMVPN network can also refer to our Configuring Cisco Dynamic Multipoint VPN (DMVPN) - Hub, Spokes, mGRE Protection and Routing - DMVPN Configuration article which fully covers the deployment and configuration of a Single DMVPN Network/Cloud - Single Tier Headend Architecture. This will provide an insight to engineers and IT Managers considering implementing a DMVPN network. Following our successful article Understanding Cisco Dynamic Multipoint VPN - DMVPN, mGRE, NHRP, which serves as a brief introduction to the DMVPN concept and technologies used to achieve the flexibility DMVPNs provide, we thought it would be a great idea to expand a bit on the topic and show the most common DMVPN deployment models available today.
