Which type of VPN uses a hub-and-spoke configuration to establish a full mesh topology?
Explanation:
Dynamic Multipoint VPN is a VPN technology that allows multiple branch offices to establish VPN connections with a central hub router without requiring a full mesh of VPN tunnels between all sites. In a DMVPN configuration, spokes establish direct tunnels with the hub router, creating a hub-and-spoke topology. However, spokes can also communicate with each other directly through spoke-to-spoke tunnels, dynamically established when needed, creating a virtual full mesh topology. This allows for efficient communication between branch offices without the need for direct VPN tunnels between all pairs of sites.
