Abstract
Dynamic Multipoint Virtual Private Network (DMVPN) by Cisco, was developed to overcome the limitations of traditional VPNs by improving their scalability, which had been a drawback. DMVPN achieves this by utilizing technologies like Multipoint Generic Routing Encapsulation (mGRE), Next Hop Resolution Protocol (NHRP), and various routing protocols. Additionally, the inclusion of IPsec is mandatory to ensure robust security measures.
