 Disclaimer: The vxlan tunnel will be removed from Honeycomb, and delete command will be executed on VPP, but VPP will just disable that interface and keep it as some sort of placeholder for next vxlan tunnel (that's VPPs behavior, so a vxlan tunnel cant be really deleted). So that's why you would still see the tunnel in VPP's CLI after delete.
