Cisco SECURE 1.0: Deploying DMVPNs

This course is included in our On-demand training solution.


Dynamic Multipoint Virtual Private Networks (DMVPNs) are a Cisco IOS Software feature that simplifies the deployment of large hub-and-spoke, partially meshed, and fully meshed virtual private networks (VPNs). In this lesson, you will learn to integrate multipoint Generic Routing Encapsulation (mGRE) with Next Hop Resolution Protocol (NHRP) and IP Security (IPSec) to deploy DMVPN on hub-and-spoke devices. After configuring all required parameters, you will verify proper DMVPN operation and learn how to troubleshoot common DMVPN issues.

Target Audience

Network professionals responsible for securing and managing their network infrastructures, who have CCNA certification, CCNA Security certification (IINS), and a working knowledge of Microsoft Windows operating systems
