    Hello,
    I am a new on EVPN-VXLAN fabrics, and I am wondring if i can configure EVPN-VXLAN fabrics with Eve-Ng ?
    I want to simulate a LAN Campus FAbric, and not Lan DC Fabric.
    Here is the target network for customer .

    Thank you

    Hi,
    Your drawing is lacking some information. But running 32 simulators at the same time in EVE-NG requires 128 GB ram and 64 CPU cores just for the Aruba CX devices. And you need some more for running the EVE-NG also.

    VSF is not supported in the simulator, it may look like you are planning to use 6300 and VSF.
    VXLAN with L3 VTEPs is not supported in the simulator.
    VXLAN and VSX works for the protocols, but fails if you try to run any traffic through the network.
    Jumbo frames is not supported in the simulator.

    I think the correct answer is, you may run some parts of your setup to verify your configurations and train on using EVPN VXLAN, but running the topology on the drawing is probably not something you can do with the simulator.

    Limit your labs and run parts of your setup and you will have the possibility test a lot of your setup.

    Hello Arne and thank you for your reply,
    Actually, i am not going to use the simulator for the 30 sites , only 3 sites will be ok for me .
    The goal for me is to familiarize myself with the VXLAN technology on aruba CX , since it is the first time to me.
    Is there any Aruba documentation explaining how Vxlan fabric works on campus network , and how we configure it with ArubaCX ?
    Thanks

    The documentation for 10.11 is here:

    Joe Neville have some excellent videos:

    Hi,
    All of Arne's points are correct. Please keep them in mind.
    Here are some VXLAN lab guides using the simulator:
    AOS-CX Simulator Lab - Static VXLAN
    AOS-CX Simulator Lab - VXLAN EVPN
    AOS-CX Simulator Lab - VXLAN Centralized L3 Gateway
    AOS-CX Simulator Lab - VXLAN EVPN Troubleshooting
    AOS-CX Simulator Lab - VNBT - Virtual Network-Based Tunneling
    For more information about the simulator, please go to: https://community.arubanetworks.com/community-home?communitykey=aa40c287-728e-4827-b062-5eff4ed6410b.
    Regards, Ruben.-

    All, 

    I created an Aruba CX Campus Spine-Leaf VXLAN-EVPN in EVE-NG. Below is the image in EVE-NG, I have attached the configuration guide in PDF and all of my findings etc. This design is based on VXLAN Centralized L3 Gateway. The VXLAN lab guides Ruben provided are extremely helpful.  Hopefully this helps. Thanks.

    Thank you for this thread. From the last post, did you get L3 VTEP working in Eve-Ng?

    I could not with my 10.07 version.

    Will it work in later releases?

    "VXLAN support with L3 VTEPs"  is listed as non-functional in version 10.11 of the simulator.
