vxlan is not instead of vlans, it is instead of gifs
vxlan is designed to pass trunks over routed network forming its own tunnel.
Just read its manual page.

Loops, broadcast storms spreading too far over long and slower links,
applications and kernels not adopting automatically for "not LAN" conditions
like they do in case of separate IP networks, extra overhead and timing issues,
poor manageability of if_bridge (unable to show/manage its forwarding tables
as opposed to newer vxlan) comparing to rich set of methods developed
for routing tables etc.
