A global organization with several branches hired a network architect to design an overlay VPN solution. The branches communicate with each other frequently. The customer expects to add more…

DMVPN (Dynamic Multipoint VPN) is designed for scalable hub-and-spoke and spoke-to-spoke IPsec VPNs, allowing branches to dynamically establish secure tunnels directly with each other. This setup minimizes latency by avoiding the hub for inter-branch traffic and supports easy expansion by adding new spokes without reconfiguring existing ones.

EasyVPN is primarily a client-to-gateway solution or for simpler hub-and-spoke designs and does not provide dynamic spoke-to-spoke IPsec tunneling for frequent inter-branch communication.

GETVPN (Group Encrypted Transport VPN) provides secure group communication for traffic flowing between members of a trusted group but does not dynamically establish on-demand spoke-to-spoke IPsec tunnels for direct communication.

L2TP (Layer 2 Tunneling Protocol) is a tunneling protocol that does not inherently provide IPsec encryption or the dynamic multipoint capabilities required for direct spoke-to-spoke communication.
