Hi,
no, this is requiring L3GW support, which is dependent on the ASIC. As of today, you need to do the routing outside of the VXLAN "fabric" with EXOS. You should contact your local SE to discuss the plans for VXLAN L3GW support (platform/sw support).
Please note that you can do VXLAN L3GW, today, on S-series and VSP 7200/8200/8400 series.
