Difference between OVA and 6400 firmware, missing configuration options (VXLAN, VRF, BGP)

  • 1.  Difference between OVA and 6400 firmware, missing configuration options (VXLAN, VRF, BGP)

    I am using a lab to test configuration changes before applying these to my hardware switches. However, a recent change I planned to make involved using symmetric integrated routing and bridging, i.e. routing VLAN traffic through a dedicated VNI across my EVPN VXLAN fabric. In so doing I plan on leaking routing information between different VRFs - ultimately neatly separating different routing VRFs for upstream routers. I mostly oriented myself after the example configuration in the chapter "example of external connectivity and IVRL with symmetric IRB" contained in the AOS-CX VXLAN EVPN Guide: Example of external connectivity and IVRL with symmetric IRB

    Example of external connectivity and IVRL with symmetric IRB
    In symmetric IRB deployment, IVRL is typically configured at the border VTEPs. At the border VTEP, host routes (published by remote VTEPS via route type-2) are installed. Similarly, the EVPN type-5 prefixes advertised by other VTEPs get installed as prefix-routes (for example, a /24 prefix for IPv4 overlay network).

    Unfortunately, I soon realised that the route-target configuration in the VRFs is not possible in the OVA firmware as it does not exist there. It does, however, exist in the actual firmware on my 6400 switches. I tried different versions of the OVA (10.09, 10.10, 10.11) and they all are missing the route-target configuration option under vrf. 

    Since it is a huge availability risk to perform these configuration change tests on my live hardware I am quite at a loss. Is it possible to achieve the same functionality explained in that chapter without these explicit commands? If so, how?

    You can check in the Aruba Switch Feature Navigator which features are available in which platforms, including the CX Emulator (VM). Because the VM does not run on actual hardware, it tries to be as close as possible to physical switches, but obviously can't emulate everything.

    Thanks for the link. There are a lot of VXLAN features not supported in the CX Simulator including a lot of VRF related ones. It's a little hard determining what feature name corresponds to which switch configuration but I am pretty sure that "EVPN - L3 VNI (VRF)" is the one I am missing. Oh well, no testing of configuration for me then.
