What is the difference between Getvpn and Dmvpn?
GETVPN is a tunnel-less VPN technology providing end-to-end security for network traffic across fully meshed topology. DMVPN provides full meshed connectivity with simple configuration of hub and Spoke. DMVPN forms IPsec tunnel over dynamically/statically addressed spokes. Better due to no multicast replication issues.

FlexVPN is Cisco’s implementation of the IKEv2 standard featuring a unified paradigm and CLI that combines site to site, remote access, hub and spoke topologies and partial meshes (spoke to spoke direct).
What is a characteristic of Getvpn?
GETVPN uses ESP (Encapsulating Security Payload), the same as traditional IPSec VPNs. It only supports tunnel mode which encapsulates the entire IP packet which adds a new IP header. There is a twist however, GETVPN uses tunnel mode with address preservation.
What is GDOI in Getvpn?
GDOI is a protocol that is used for Group Key and SA management. It uses ISAKMP for authenticating the Group Members (GMs) and Key Servers (KSs). GetVPN only supports time-based SA expiry as it does not have any information on the amount of traffic sent between peers.
