As Florian mentioned, there are already some key components for EVPN based VXLAN that work:
- L3 underlay (OSPF or BGP)
- MP-BGP EVPN control-plane
- pure L2VNI
Aruba is very aware on these OVA limitations (no ECMP yet, no L3 VTEP yet, no L3VNI yet) and impact on self-training,
but I would say that 80/90% of the EVPN learning being around control-plane, you can already do a lot with the existing OVA for learning EVPN and more. For UBT, this is different and this is not available yet.
OVA is getting improved release after release, not at the pace we all would like, but this is not as straightforward as assumed in this forum.
Thanks for exchanging on this topic as he OVA is a great tool to learn.

Subject: Aruba Virtual Switch OS CX 8400 Dynamic Segmentation Possible?
I'd love to have virtual AOS-CX too with EVPN/VXLAN + dynseg support. In the end you can already run VXLAN, EVPN, GRE tunnels whatnot on linux so this is not something that would require specific hardware or anything. CX is LInux based so I don't think it would be that hard to actually have the features that everyone really needs to lab with :)
This is one reason where for example Arista shines, you can have the exactly same software running in a virtual switch and you can practice/lab huge scenarios. Their webinars are also awesome, and they had a really good point in one of their automation webinars: software guys can do test scenarios for everything in their software, networking guys just do "reload in 15" and then just pray their configs would work and they wouldn't lose connectivity :) If we had good enough virtualization environments with all the features we would be sure that the configs we're going to push are going to be fine as they were already tested in a lab environment.
If we need to get hw for labbing to do something like EVPN/VXLAN between two DCs it will cost huge amounts of money to build even remotely something to simulate the setup. If we could just spin 50 switches in virtual machines we would be able to test all our configs before pushing it to production.

Should be awesome if this could be possible to practice for the new ACMX training. But thinks isn't easy to virtualize this.

Hello,
Unfortunately, dynamic segmentation (User Based Tunneling: switch to Mobility gateway) is not yet supported on the AOS-CX OVA.
