TKG with Antrea in NSX-T

Hi Everybody

When using TKG in vSphere by default it uses the Antrea CNI which uses a Geneve overlay on top of the existing NSX-T Geneve overlay. That is, there are two Geneve encapsulations.

In general, I see the point of using overlays in Kubernetes so the network is flat from Kubernetes point of view and the address space doesn't overlap with the existing infrastructure but what is the point of doing two overlays, besides adding overhead?

Thanks

NSX-T and Antrea are independent, each with its own control-plane. That's why there are two encapsulations.
