In the context of DMVPN (Dynamic Multipoint Virtual Private Network), IPSec is indeed a requirement. DMVPN leverages IPSec as its encryption protocol to secure the communication between remote sites. This is essential for providing confidentiality, integrity, and authenticity of the data being transmitted across the network.

IPSec establishes a secure tunnel between the various endpoints in a DMVPN configuration, enabling the encapsulation and encryption of the traffic. The implementation of IPSec is crucial because DMVPN itself does not provide security; it relies on IPSec to achieve the necessary security protocols for data transmission.

The other options, while relevant in various networking scenarios, do not meet the criteria for DMVPN functionality. Static routing is not required as DMVPN is designed particularly for dynamic routing capabilities, allowing for more flexible and adaptable network configurations. Point-to-point GRE tunnels are indeed part of DMVPN’s architecture, but they are not a standalone requirement. Lastly, while a basic routing table is helpful for any networking scenarios, it is not a specified requirement for DMVPN, which primarily focuses on the dynamic aspect facilitated by protocols such as NHRP (Next Hop Resolution Protocol).
