IPsec

In DMVPN, tunnels are secured using the IP Security (IPsec). IPsec is a suite of protocols that protect network communication at the IP level (Layer 3).

Note: The vRouter supports the AES options with 128-bit or 256-bit Galois/Counter Mode (GCM), which provides improved efficiency and performance.
