Nexus 9K - Encrypted GRE Tunnels

[vxlannnn]

Hello,

Is it possible to encrypt GRE tunnels on the Nexus 9K platform?

I can't seem to find any instructions within the 9K documentation.

I'm looking to create a tunnel between three 9Ks and advertise routes between these labs over that tunnel - however there is a requirement that the tunnels are encrypted. The configuration of the actual tunnels is no issue and works as expected.

Could I achieve something similar using VxLAN if that supports encryption?

GRE Tunnel is just tunnel, Entryption different on top of it. that you need to look the guide and support.

But I cannot find any guide specific to Nexus which is why I posted here.
