The failure is due to a loop that get's created as a side-effect of adding the Host data-interface (eth2 in case of vagrant vm based setups) to all vlans. Since vxlan implementation also internally uses a vlan-tag for local forwarding. As a result the incoming vxlan packets also get put back on the Host interface resulting in a loop.
A possible fix is to add host interface only to the vlans created for vlan-based networks.
Below are the test logs of the failure:
