[FROG] l2vpn evpn, vxlan without bridge.

Hi, I set up FRR routers as VTEP for a setting where all trafic on the vxlan will originate on the routers. I setup the BGP l2vpn evpn family address, but I cannot get FRR to announce its routes (type 2 or type 3) if the vxlan interface is not in bridge. I end up bridging it with a dummy interface, but for me it is an ugly workaround. Is there a way to avoid this bridge ? -- Erwan David
